A variable gain and output power CMOS PA with combination switch controls

摘要：

A variable gain and output power CMOS power amplifier is presented in this paper. With combination switch controls of three cascode devices in the driver stage, the power amplifier can achieve a variable power gain and output power (seven types). The power amplifier was fabricated in 0.35-u.m standard CMOS process, and is able to deliver a power gain of 10.527 dB and an output PldB (1-dB compression point) of 9.3~20.3dBm together with a PAE (power-addedefficiency) of 4.1-36.5％ at 915MHz frequency and 3.3V supply respectively. Key words: CMOS; power amplifier; variable gain; switch control.
