Abstract :
We have developed a 79 GHz CMOS power amplifier (PA) with temperature compensation implemented using 40 nm CMOS technology that suppresses the variation of small-signal gain and the degradation of linearity within 0.8 dB in the temperature range from 0 to 100°C. The PA consists of an on-chip temperature sensor and four-stage common-source NMOS amplifiers. The temperature-compensated PA operating at 100°C achieved a small-signal gain of 15.7 dB, a 12 GHz bandwidth and a saturated output power (Psat) of 6.8 dBm with 96.2 mW power consumption at a supply voltage of 1.1 V.
