Abstract

A fully-integrated common-gate UWB LNA employs a stagger-compensated series peaking technique to extend bandwidth, and a capacitor cross-coupled g_m-boosting technique to reduce NF and power. A simple input matching scheme obviates the use of multiple inductors and complex filters. For two versions in 0.18 mum CMOS, BW extension factors are 4.1times and 4.9times, -3dB bandwidths are 1.3-10.7 GHz and 1.3-12.3 GHz, NF are 4.4 dB and 4.6 dB, peak S₂₁ are 8.5 dB and 8.2 dB, and peak IIP3 are 8.3 dBm and 9.1 dBm, respectively. Each differential LNA draws 2.5 mA from 1.8 V
