This letter reports power amplifiers for 77-GHz automotive radar applications in a 90-nm LP (lowpower) 1P6MCMOS technology. The three-stage single-ended PA has a 12.4 dB gain and a+9.1- dBm saturated output power and the two-stage differential PA has a 11.3 dB gain and a+11.4-dBm output power at Pin=1.9 dBm. This is the first letter to report CMOS PA characteristics over full automotive temperature range ( -40∘c to 125∘c ) at 77 GHz range.
