Transceiver Design3. Transceiver Design3.1 IntroductionThe drive for lower cost and hence system-on-chip (SoC) design has inevitably brought up CMOS technology as a serious contender. The cost of low complexity subcircuits such as amplifiers and mixers is determined by primarily packaging and testing, rather than chip area. On the other hand, with single-chip transceivers and the prospect of integrating the digital baseband processor along with the RF and analog functions, the cost equation is heavily weighted by the chip area and therefore the integrated circuit (IC) technology.3.2 Technology Trends in RFIC’sThis section attempts to provide some insights into the current trends and research in the area of low cost RF front ends. Currently, a great amount of research is underway to improve the power e……
