A W-Band 6.8 mW Low-Noise Amplifier in 90 nm CMOS Technology Using Noise Measure

Abstract

A W-band low-noise amplifier consisting of seven common-source transistor stages is designed using noise measure as the figure of merit for circuit optimization. Fabricated in 90 nm CMOS technology, the die size is 0.38 mm(2), while the core active area only 0.1 mm(2). The circuit gives peak power gain of 21.5 dB at 90 GHz and noise figure of 8.3 dB, with dc power consumption of only 6.8 mW.
