The purpose of this paper is to design and implement a fully integrated low‐phase noise and large tuning range dual‐band LC voltage‐controlled oscillator (VCO) in 0.13 μm complementary metal oxide semiconductor (CMOS) technology.

Two parallel‐connected single‐band VCOs are designed to implement the proposed VCO. Adopting a simple and straight‐forward architecture, the dual‐band VCO is configured to operate at two frequency bands, which are from 1.48 GHz to 1.78 GHz and from 2.08 GHz to 2.45 GHz. A band selection circuit is designed to perform band selection process based on the controlling input signal.

The proposed VCO features phase noise of −104.7 dBc/Hz and −108.8 dBc/Hz at 1 MHz offset frequency for both low corner and high corner end of the low‐band operation. For high‐band operation, phase‐noise performance of −101.1 dBc/Hz and −110.4 dBc/Hz at 1 MHz offset frequency are achieved. The measured output power of the dual‐band VCO ranges from −8.4 dBm to −5.8 dBm and from −9.6 dBm to −8.0 dBm for low‐band and high‐band operation, respectively. It was also observed that the power differences between the fundamental spectrum and the nearby spurious tone range from −67.5 dBc to −47.7 dBc.

The paper is useful to both the academic and industrial fields since it promotes the concept of multi‐band or multi‐standard system which is currently in demand in the telecommunication industry.

Islamic finance and Halal product sectors are thriving successfully. This chapter is a general review of the perception of Asian consumers on Islamic finance and Halal sectors in the global Halal economy.

The first section will briefly describe the Halal concept in both Islamic finance and Halal industries, and the growth of both sectors in Asian countries. The second part highlights the review of Asian consumers’ perception towards Islamic finance products and Halal products.

The review found that the consumers’ perception towards the Islamic finance products and Halal products is distinctive. This is due to the diversity of Asian countries in terms of geography, religion, culture, ethnic, school of thoughts (madzahib), income per capita and government’s involvement.

The third part of the chapter concentrates on planning towards Halal marketing, which involves the move and future challenges in different layers of industries to gear up and strengthen the Halal economy.

This paper discusses the urban management challenges in the Greater Kuala Lumpur area. Before examining Greater Kuala Lumpur's economic and social environment, we will look at the factors that make it a competitive and fiscally sound entity. When considering urban development and redevelopment, we consider how proposed and ongoing projects, as well as plans, hierarchical links, and road networks, contributed to the increase. Because there is no urban growth boundary, land use change and rural encroachment, as well as environmental degradation and the impact of national economic projects on urban expansion, are both rapid and linear in the analysis. This paper also considers how to manage linear development that results in the creation of new suburbs. Finally, we propose strategies for achieving sustainable urban expansion and management by balancing the financial and governance capacities of Greater Kuala Lumpur local governments.

This study aims to examine the nonlinear effects of board size and board independence on the corporate sustainability performance of listed firms worldwide.

This study uses the global environmental, social and governance (ESG) dataset from the Thomson Reuters database, which includes a sample of 23,766 firm-year observations from 33 countries from 2011 to 2022.

The results indicate that board size and independence have positive impacts on corporate sustainability performance; however, these relationships are nonlinear. The authors find an inverted U-shaped relationship for board size. After the optimal point, the positive relationship between board size and corporate sustainability performance becomes negative. Board independence, however, has a positive exponential relationship in which the positive effect increases exponentially after the optimal point. The results are robust to a battery of tests, including alternative measures for corporate sustainability performance, board independence and different estimation procedures.

This study illustrates empirical evidence on the nonlinear effect of board size and board independence on corporate sustainability performance, which explains the mixed evidence involving board size and independence in corporate sustainability literature and offers a complementary research approach in the literature on board dynamics.

This study has practical implications for investors aiming for sustainable and ethical investment choices, as they should be mindful of matters relating to board composition, particularly the appointment of independent directors and ideal board size.

Extensive empirical evidence has examined the relationship between corporate governance variables and corporate sustainability performance. This study introduces the effect of the nonlinear relationship between board size and board independence on corporate sustainability performance using international evidence.

The study aims to investigate the students' perceptions on the teaching of Islamic education in the Malaysian secondary schools. The study will also look into the students' attitudes based on their personal self-evaluation as well as to examine the relationship between these two variables.

The study employs quantitative and survey research design. The instrument used for data collection was a questionnaire which is distributed to samples that were randomly selected in representing the selected population among students of Malaysian secondary schools. The instrument used is a modification of instrument developed by Ab Halim et al., Ahmad Munawar and dan Azhar. The pilot study done shows a high reliability of 0.924 for the assessment of Islamic education teachings and 0.869 for the aspect of Islamic attitudes. 3,262 Form 4 and 6 students from selected schools in Malaysia participated in the study. The data were analyzed to display the frequency, percentage, mean, standard deviation and Pearson's correlation.

The study revealed a high level of mean on the aspect of students' evaluation on the teaching of Islamic education at their schools. It was also found that the level of students' attitudes was also high, i.e. 4.26. There was a significant relation between the students' perceptions on the teaching of Islamic education and their attitudes (r=0.740, p=0.000).

The implementation of teaching and learning strategies and new approaches are some of important elements in the teaching and learning process of Islamic education. This study shows that the lesson of Islamic education has significant and strong relationship with the students' attitudes in their daily lives. Since the students felt that the lesson of Islamic education was important for them, teachers should improve the lesson on Islamic education by using different types of teaching methods, technique application and motivational approaches. The teaching of Islamic education should not only focus on theoretical aspects but must also emphasize on practical implementation of Islamic knowledge.

This paper describes the religious teaching and learning in schools which has significant relationship with the students' daily attitudes. A new area of research can be conducted to explore the most important factors of teaching and learning that contribute to the students' attitudes development. These findings can also be used by educators to improve the quality of the lessons based on the students' evaluation.

This research aims to examine and compare differences in waṣiyyah wājibah (obligatory bequest) (WW) practices in Malaysia and Indonesia.

This is an exploratory qualitative research, employing a thematic analysis approach. Six Muslim Wills (State) Enactments [Enakmen Wasiat Orang Islam (Negeri)] in Malaysia, Islamic Law Compilation (Kompilasi Hukum Islam) in Indonesia, two fatwas (ruling in religious matters) and one court case from each country are analysed. Data is collected from official government websites and other reliable search engines.

First, the findings show that the WW practice in both countries is similar regarding the quantum of the beneficiaries' entitlement. However, the practice varies between both countries in terms of the types of beneficiaries and how the bequest is distributed. Second, this study shows the potential of WW as an estate planning instrument to complement the existing instruments in each country, especially when addressing family members who are not entitled to succeed by farāʾiḍ (Islamic inheritance law).

The provision of relevant laws and regulations regarding WW needs to be formulated to guarantee the well-being of dependants. The differences in practice between the two countries can be a guideline to expand the WW scope and context to other Muslim countries.

This study is the first attempt to compare WW between two Muslim-majority countries focusing on relevant laws, court cases and regulations.

In Malaysia, Get-Rich-Quick scheme (GRQS) is one of the financial fraud activities prohibited under Malaysian law. The common facet of such schemes involves plans that promise unrealistic rates of returns, and this new scheme continues to proliferate every year as the list of illegal investment companies and websites are growing. Indeed, GRQS will remain proliferating as long as there are people who are easily lured by the promise that wealth can be generated with little skill, effort or time. This paper aims to explain the phenomenon of GRQS in light of the existing laws in Malaysia. This paper also highlights the current development of Australian law pertaining to GRQS for comparative purpose.

This paper mainly relies on statutes as its primary sources of information. As such, this paper analyses the scope and provisions of the relevant laws that regulate GRQS and compare the existing GRQS provisions that are equivalent with Australian law.

Malaysia has comprehensive laws to combat GRQS activities. However, these laws are far from perfection, and only with immediate amendments, GRQS problems can be resolved more effectively. One of the weaknesses of current Malaysian laws to tackle GRQS is the lack of more stringent punishment against the operators of GRQS as well as the participants of the scheme. A comparison with equivalent GRQS law in Australia demonstrates that Australian laws provide a wide range of punishment to the operators and prohibits participation in GRQS. More importantly, Australia regards the offense as a strict liability offense where the mens rea or guilty mind of the perpetrators is exempted. Indeed, numerous proceedings have been instituted in the Australian Court against the operators and participants of GRQS.

This paper analyses the scope of relevant laws in Malaysia to combat GRQS and examines the strengths and weaknesses of these laws. This paper also compares Malaysian law with equivalent GRQS-related laws available in Australia. This paper further suggests that Malaysia should regulate sterner punishment for operators and participants of the scheme and that the offense is categorized under a strict liability offense where the mens rea or guilty mind of the offender is exempted.

This paper aims to discuss the potential of al-Wasatiyyah (hereafter, AW) value concept for human sustainability (hereafter, HS) values and its applicability to civil service practice (CSP) in Malaysia. AW is a derivative of an Arabic word that means excellent, moderate, just and professional.

This paper explains the potential of AW concept for HS both in epistemological and ontological perspectives with a focus on CSP. It focuses on the AW value concept according to Ibn Miskawaih and its applicability in CSP in Malaysia. Using content analysis and “integration perspective” between AW and contemporary Malaysia CSP practice, several questions were unlocked in this paper. They include the following: what are AW values for HS? What is the standard of value for sustainable CSP in Malaysia? And how HS from AW perspective can generate quality CSP in Malaysia?

It is found that AW can extend and enrich the meaning of value for HS and subsequently the civil service quality in Malaysia. Findings showed that AW can offer a holistic approach through four AW core values. The study also showed that AW is embedded indirectly in Malaysia CSP before it was highlighted under Najib Razak administration. This study suggests continuous emphasis on AW values in three service areas, namely, service requirements (SR), service priorities (SP) and service quality (SQ).

The limitation is to bring the value concept into the HS parameters. HS is indexed by quantitative indicators including economy, health and education achievements, rather than value concept. This study tries to expand the potential and importance of value as an indicator for HS. That is through a concept named as AW.

AW values and approaches are perceived to be a potential focus system for HS and resource building in Malaysian civil service.

Extending the meaning of HS through the application of AW concept is perceived to enrich social values and development.

This paper argues that current discussion on HS is not fit for all purposes because it lacks human great values. This paper subsequently argues AW concept as potential HS values, especially for CSP, in Malaysia.

The purpose of this study is to assess small and medium-sized enterprises (SMEs) owners’ intentions to participate in waqf, involving two countries, which are Malaysia and Indonesia, using the theory of planned behavior. SMEs are the backbone of many economies, representing 95% of all companies worldwide and accounting for 60% of employment. Based on this fact, this paper analyzes the influence of religiosity, knowledge and attitude to predict the intentions of SMEs’ owners in waqf participation in Malaysia and Indonesia.

Data were randomly obtained from 175 SMEs owners from Malaysia and Indonesia with the Statistical Package for the Social Sciences (SPSS) used for analysis.

The empirical analysis data suggest that knowledge and attitude show a significant impact on the intentions of SMEs’ owners to participate in waqf, while religiosity does not have a significant impact on the intentions of Malaysian and Indonesian SMEs’ owners to participate in waqf.

This study aims to assist SMEs in Malaysia and Indonesia to formulate appropriate strategies and marketing using waqf for the sustainability of SMEs which represent more than 90% of business establishments in both countries. The strategy is a necessity, especially because the government is targeting to promote a sustainable Islamic financial system, improve governance policy and halal industry for SMEs, strengthen the development of Malay Reserve land, providing as financial independence to higher learning institutions and invest in digitalization and advanced technology through waqf funds. Therefore, both countries should take the initiative to provide training to equip SMEs with extensive knowledge through multiple platforms to further encourage their participation in waqf.

Because of the increasing interest in waqf participation both in Malaysia and Indonesia, this study claims three essential contributions. First, it aims to examine the intention of SMEs in waqf participation among the business owners in Malaysia and Indonesia. Second, the study findings are expected to benefit the development of literature in accordance with Islamic social finance, particularly waqf. Third, this study provides an insight into the inclusive knowledge and attitude of SME owners and their intention to participate in waqf.

The purpose of this paper is to introduce a conceptual framework that can facilitate investigations concerning the impact of marketing communication and financial consideration on the relationship between customer attitude and purchase intention of Islamic banking products and services.

This conceptual paper is structured based on the extant literature; it provides a review of theoretical perspectives, highlights the gap and illustrates the significance for developing a framework.

The authors identify notable patterns and limitations in previous empirical studies. Specifically, despite increasing interest in Islamic banking customer behavior, prior research has not given much attention to explore moderating effects on the customer attitude–intention link. This has left researchers and bank managers with very limited information to explain the conditions that enhance customers’ attitude and intentions toward Islamic banking products. Based on this backdrop, the paper displays a viable research model with propositions that assess potential moderating effects on the domain relationship.

This paper contributes to Islamic banking and management literature because prior research has predominantly focused on variables that directly influence customers’ behavior. This novel conceptual framework enables managers to better understand their customers and has implications for emerging themes, such as formulating strategies for specific customer groups and internationalization process. In addition, this paper provides a starting point to empirically examine whether and how the proposed moderators affect the link between customer attitude and behavioral intentions to purchase Islamic banking products.

To the best of knowledge, this is the first attempt to introduce relevant moderating variables for investigating the attitude and intention nexus in an Islamic banking context. Furthermore, the authors propose a new measure, namely, profit-loss sharing proportions which could enhance customers’ intention to purchase Islamic banking products.
