A 13.5–19 GHz 20.6-dB Gain CMOS Power Amplifier for FMCW Radar Application

A Ku-band wideband power amplifier (PA) for frequency modulated continuous wave (FMCW) radar application is proposed and implemented in 65-nm bulk CMOS technology. To obtain low group delay, low amplitude ripple, and wide bandwidth, the transformer and inductor-based matching network is designed to meet the requirements. Including pads, the PA occupies a compact chip area of 0.62 mm2. Consuming 11...
