Abstract
A high output power and high efficiency power amplifier (PA) is designed for 60 GHz wireless point-to-point communication using IBM 90 nm CMOS process. A high efficiency is achieved through the utilization of cascode structure with floating n-well and differential inductor to resonate out the parasitic capacitances. To further boost the output power, four PA units are combined together through power combining network. This PA achieves saturation power of 18.3 dBm and peak PAE of 24.3% at 60 GHz in simulation.
