Abstract
An Ultra low-power ultra-wideband low noise amplifier (UWB-LNA) is presented in this paper. The proposed LNA utilizes a common gate input stage followed by a common source stage acting as an output stage (CGCS) in a current reuse configuration. Forward Body-Biasing (FBB) technique is adopted for ultra low-power dissipation. The design achieves high post-layout gain with a maximum of 12.5 dB and a minimum post-layout noise Figure of 3.9 dB. The proposed design drives only 1.68 mA from a 0. 65V power supply. Within the UWB frequency spectrum of interest, the input and output return loss are less than-10 dB and -6dB, respectively. This LNA circuit is designed and simulated in 130nm CMOS Technology.
