A Compact 60 GHz LNA with 22.7-dB Gain and 4.4-dB NF in 40nm CMOS

Abstract

This paper presents a compact low-noise amplifier (LNA) design for 60 GHz phased-array applications. Utilizing single transformer-based 4th-order resonators for input and inter-stage matching, a compact core area of only 0.08mm2 is achieved. A unit transistor-cell layout design technique for millimeter-wave (mm-Wave) circuit design is adopted to reduce the uncertain high-frequency coupling effects, leading a peak gain of 22.7dB. A 4.4-dB noise figure (NF) and a 3-dB bandwidth from 54 to 63 GHz are achieved based on the post layout simulation results, with a total power consumption of 29.9 mW.
