An overview of recent advances in CMOS T/R switch designs

Recent advances in design of transmit/receive (T/R) switches in complementary metal oxide semiconductor (CMOS) technology for radio transceivers are reviewed in this paper. First, the evolution of wireless communication systems and CMOS technology are introduced for the purpose of design of T/R switches. Then, typical T/R switch topologies, key performance parameters, and device circuit models are described. Next, the important circuit techniques and concepts developed specifically for CMOS T/R switches are discussed. Finally, reported CMOS T/R switches are summarized and future design issues are identified.
