The book opens a magic miniature world of electronics to the reader. The book addresses what small means in terms of electronics and what clean means in terms of modern electronic technology. Consequently, the reader understands why the most advanced civilization of the ancient world ¿ the Egyptians ¿ was not capable to do electronics. The book also discusses functionalities of the low-voltage electronic components with the aim to implement them in electronic circuit design. At the same time, it also opens the space of electronic component design to the readers be it discrete or integrated. The book has an introduction section, 11 chapters, an appendix, index, and list of literature. Appendix A discusses a set of solved problems, Appendix B presents SPICE simulation examples, and Appendix C presents component numbering in marketing environment.

This book discusses synthesis of Gm-C filter for modern radio frequency systems. Analogue filters are an inevitable part of the chain of signal processing in modern radio and telecommunication systems. Among the technologies implemented for these purposes are the so-called Gm-C filters which are built of operational transconductance amplifiers and capacitors. This technology allows for integration of the filter into a CMOS system-on-chip so making it very attractive for application in low-power (battery operated) devices. The objective of this book is to achieve three goals: (1) to fully describe the circuit synthesis procedures for parallel, cascade, and a realization based on LC prototypes; (2) to make a thorough evaluation of the advantages and disadvantages of these methods and to recommend the ¿preferable¿ one; and (3) to create an extensive table of element values of cascaded Gm-C filters realizing the best-known low-pass filter functions. The book will influence the design community to embrace this technology even for non-communication applications.

Further, it discusses new procedures to improve the selectivity of all polynomial filters by introducing transmission zeros, such as filters with multiple transmission zeros on the omega axis, as well as phase correction of selective filters for both low-pass and band-pass filters.
