Abstract
This paper presents the design of a low noise amplifier (LNA) for automotive radar application operating at 76-77 GHz. The LNA consists of 5 cascade common source amplifiers. The output of each stage is positioned close to the gate of the next stage creating a LC resonance output load, therefore complex interstage matching networks are eliminated. Moreover, transmission lines (T Ls) are utilized to create matching and load inductors. As a result, chip size is significantly reduced. The proposed LNA is implemented in a 65 nm CMOS technology and measurement results show 11 dB voltage gain, and 7.8 dB noise figure (NF) while dissipating 21.5 mA from 1.2 V supply. © 2012 IEEE.
