Low Power Ultra-Wideband Low-Noise Amplifier for UWB Receiver

Abstract

In this paper, a 4-13GHz low power low-noise amplifier (LNA) for UWB based on two-stage topology is presented. Wideband matching, low noise figure (NF), and low power are achieved by using a gate inductor-assisted impedance matching and a current reuse feed-forward noise cancellation techniques, respectively. The low power consumption UWB LNA is designed using standard 65 nm CMOS technology. This LNA achieves a 16.9 dB gain, a 4.3 dB minimum NF. The consumes 9.4 mW from a 1-V supply.
