A CMOS 3?12-GHz Ultra wideband Low Noise Amplifier by Dual-Resonance Network

Surabhi Katiyar | Bhawna Trivedi ^[2]

Abstract: A low-power and high power-gain (S21) ultra wide-band low noise amplifier (UWB LNA) with flat noise figure (NF) based on global foundries 0.13-m CMOS technology is reported. The load effect of common-gate (CG) topology is applied with dual-resonance load network for both wide band input matching and NF flatness. Combined with inductive-series peaking technique, the frequency response of CG-common-source cascade topology is further extended. The LNA circuit achieves the high and flat power gain of 13.5 1.5 dB with input return loss better than 13dB and a flat NF of 4.3 dB 0.4 dB for frequencies 3-12 GHz. The fabricated LNA occupies a die area of 1.09 0.8 mm2 including pads and draw 8.5 mW from 1.2 V dc supply.
