Abstract

A 2-stage 24 to 28 GHz reconfigurable CMOS power amplifier (PA) is designed in a 22nm fully-depleted silicon-on-insulator (FD-SOI) technology. The differential PA uses stacked FETs and digitally-controlled neutralization capacitors and output matching capacitors with adjustable body-bias and on-chip baluns to increase output power POUT, reconfigurability, and wideband performance. Post-layout SPICE simulations show S21 of 27 dB, peak power-added efficiency (PAE) of 29.1% at POUT=17.5 dBm and P1dB =13 dBm can be achieved at 28 GHz. The digitally-controlled neutralization caps can tune S21 by 6 dB at 28 GHz, while varying body bias of the FD SOI NMOS can enable ~2 dB fine gain tuning, and the output matching caps can further optimize PA's performance for intelligent SoC applications.
