The challenges in the design of CMOS millimeter-wave(mm-wave) transceiver for Gbps wireless communication are discussed.To support the Gbps data rate,the link bandwidth of the receiver/transmitter must be wide enough,which puts a lot of pressure on the mm-wave front-end as well as on the baseband circuit.This paper discusses the effects of the limited link bandwidth on the transceiver system performance and overviews the bandwidth expansion techniques for mm-wave amplifiers and IF programmable gain amplifier.Furthermore,dual-mode power amplifier(PA) and self-healing technique are introduced to improve the PA’s average efficiency and to deal with the process,voltage,and temperature variation issue,respectively.Several fully-integrated CMOS mm-wave transceivers are also presented to give a short overview on the state-of-the-art mm-wave transceivers.

Dualrthermore, dual -mode power amplifier (PA) and self-healing technique are introduced to improve the PA’s average efficiency and to deal with the process, voltage, and temperature variation issue, respectively .Several fully-integrated CMOS mm-wave transceivers are also presented to give a short overview on the state-of-the-art mm-wave transceivers.
