Preface

In the past several decades, the demand for high-speed, high reliable commercial and consum‐ er electronic devices has increased exponentially. New technologies, architecture renovation, and new materials have been applied to the developed electronic circuit systems. The eight chapters in this book volume aim to introduce emerging advanced circuit design, structures, and applications, including ZnO nanomaterials, millimeter wave, energy harvesting circuitry,

Chapter 1 describes a novel self-starting DC-DC converter circuit using SiC for power elec‐ tronic applications in up to 300 °C environments. The work presented in this chapter could be of interest to professionals who work in the field of power electronics. Chapter 2 presents ZnO nanomaterial-based piezoelectric structure design in the applications of polycrystalline solar cells. Based on the design, a prototype for energy harvesting operation was built and tested in a variety of irradiance operating conditions. Chapter 3 introduces a new nanoarchi‐ tecture for quantum-dot cellular automata principles and design, especially for high-speed digital circuit applications. Chapter 4 proposes an emerging millimeter wave receiver de‐ sign, which would be of interest to the readers working on this frontier technology. The multiport circuit design work shown in this chapter can be a useful reference for millimeter wave engineers and researchers. Experimental results validate the theory and performance of this design. Chapter 5 discusses another emerging technology, compressive sensing. Compressive sensing has become an attractive technique in many applied research and en‐ gineering fields, such as big data, image processing, radar system, and wireless sensor net‐ works. This chapter implemented compressive sensing technique in radar and localization applications. Chapter 6 gives a review on two popular memory technologies, namely, SRAM and DRAM. A new design of P-3T1D DRAM cell with much faster reading time is proposed for high-speed embedded system memory applications. Chapter 7 presents three small-scale wind energy harvester circuits for high-voltage applications. The methods, de‐ signs, and measurement results given in this chapter can be useful to energy harvesting cir‐ cuit design engineers. Chapter 8 describes an experimental work on characterizing electrical nonlinear bimodal transmission line. The experimental approach proposed in this work al‐

These eight chapters cover a wide range of topics: from new materials and architectures to emerging technologies and advanced circuit design. This high-quality book volume would not have been possible without the collaboration of the authors, the reviewers, and the staff at InTech Open who assisted in the initial preparation, quality check, and final production phases. I would like to thank all of them for their invaluable work and time in producing this book volume. I hope that the readers enjoy this book volume and find it as a good refer‐
