一款应用于5G毫米波通信的23.7～35.8 GHz宽带低噪声放大器
A 23.7～35.8 GHz wideband low-noise amplifier for 5G millimeter-wave communication
摘要
Abstract
This paper presents a design of a broadband low-noise amplifier(LNA)for 5G FR2 applications based on a 40 nm CMOS technology.A three-stage differential cascode topology was adopted,incorporating an out-of-phase dual-coupling gm-boosting technique to achieve wide input matching and improved gain.An inductive feedback common-gate shorting technique was employed,resulting in a 5.46 dB improvement in maximum stable gain and a 9.95 dB enhancement in output 1 dB compression point.A hybrid interstage wideband matching network was implemented using a transimpedance peak-flattening and staggering method,achieving a 12 GHz bandwidth.Post-layout simulation results show that the LNA exhibits a peak gain of 13.5 dB,a 3 dB bandwidth from 23.7 to 35.8 GHz,a fractional bandwidth of 41%,a minimum noise figure of 5.74 dB,and an input 1 dB compression point(IP1dB)of-11.8 dBm.关键词
