Abstract

A new wideband amplifier, which is suitable for ultra-wideband (UWB) system, is proposed in this paper. The proposed amplifier achieves wideband input matching and bell-shaped overall frequency response by combining the frequency response characteristics of a high pass filter and a conventional amplifier, respectively. The simulation results based on a TSMC 0.18 mum CMOS technology show a peak power gain of 10 dB, input return loss (S₁₁) of larger then 10 dB over the -3 dB bandwidth from 2.7 to 9.3 GHz, and minimum noise figure of 3.3 dB in pass-band. The wideband amplifier dissipates 7 mA from a 2 V supply
