Abstract :
A fully-integrated common-gate UWB LNA employs a stagger-compensated series peaking technique to extend bandwidth, and a capacitor cross-coupled gm-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
