A two-stage mm-wave PA with 18.5% PAE in 65 nm CMOS

Abstract

A two-stage mm-wave power amplifier (PA) is presented. Designed in a 65 nm CMOS process, the PA employs capacitive neutralization in each stage for increased differential isolation and gain. Baluns are used for single-ended input/output signal to balanced signal conversion, and the interstage matching consists of a 2:1 transformer. With a 1.2 V supply, at… (More)
