An Efficient Band CMOS LNA for Satellite-Based Remote Sensing Application

Abstract

The paper demonstrates an efficient band CMOS LNA for satellite-based remote sensing application using 45 nm CMOS technology. The designed LNA comprises of a two stage cascode amplifier with shunt resistance feedback and dual inductive peaking (SRF-DIP) technique with source and gate inductive degeneration. The received band is 35.7 GHz that ranges from 61–96.7 GHz. The maximum power gain is 22.2 dB at resonant frequency of 74.7 GHz. The minimum noise figure is 1.25 dB at 60 GHz. The noise figure and power gains are calculated theoretically as well. The DC current I<inf>d</inf> is measured between 20–25 mA for the drain voltage of 0–1.2 V. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
