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 67 GHz, measurements show a gain of 16.8 dB, a 1dB-compression point (P1dB) of 8.4 dBm and a saturated output power (Psat) of 11.8dBm, with a peak power added efficiency (PAE) of 18.5 %. The PA core occupies an area of 100 um x 300 um.
