Abstract

A 90nm CMOS technology has been used as the baseline for a low-cost RF-CMOS platform, with improved analog/RF performances of the active and passive devices. The 65 nm gate length NMOS exhibits 240GHz peak f_max and 170GHz peak f _T. A peak Q of 40@5GHz is measured for a symmetrical 2.7 nH above-IC inductor. This combination leads to a world record performance of a monolithic 5 GHz RF CMOS low noise amplifier presenting a very high gain of 18dB and very low noise figure of 1.5dB, for only 4.8mW power consumption.
