Preface
Software-defined radios (SDRs) that are capable of transmitting and receiving modulated signals in any frequency band have long been desired. They are very attractive, especially as mobile devices, since mobile devices need to be compact even if they are compliant with many different wireless standards. In fact, recent mobile devices are required to offer an enormous range of wireless standards (e.g., 2G/3G/3.5G/3.9G/4G cellular, WLAN/WPAN, GPS, broadcasting). For many years, various aspects of SDRs have been investigated and many technologies for realizing SDRs have been developed. However, it is still difficult to realize a practical SDR device. This is mainly because conventional RF front ends are not sufficiently flexible to satisfy the requirements for all modulation schemes and frequency bands. SDR transceivers must satisfy quite a diverse range of requirements depending on the wireless standard. For example, the frequency bands required are widely spread between 400 MHz and 6 GHz. On the other hand, SDR transceivers are also required to have competitive performances (in terms of power consumption, sensitivity, etc.) with those of other single-band transceivers. A key idea for realizing SDR transceivers has recently been proposed: digitally assisted analog and RF circuits. Many circuit applications that use this concept have been reported and they are highly flexible. Thus, SDR transceivers are fairly close to becoming a reality. This book introduces potential circuits for SDRs, including RF, analog, and mixed-signal circ
