Design and implementation of a 62–77 GHz low noise amplifier in 90 nm CMOS

Abstract

A 62 to 77 GHz broadband low noise amplifier (LNA) using a low-cost 90 nm standard CMOS technology is designed and implemented. From the measured results, the proposed LNA has a peak gain of 10dB at 70 GHz, a 3dB bandwidth is 15 GHz from 62 to 77 GHz, an output reflection coefficient (S22) is better than -4dB, an input reflection coefficient (S11) is lower than -10dB and the power consumption of the LNA is 17.6 mW. In addition, the simulated noise figure (NF) is 7.6 dB at 70 GHz and lower than 8.5 dB entire bandwidth.
