Abstract

A CMOS distributed amplifier (DA) intended for ultra-wideband (UWB) wireless applications is presented. The proposed distributed amplifier employs current reuse technique to achieve low power consumption. This work is implemented in 0.18-mum CMOS technology and shows a 8 GHz bandwidth. The amplifier provides a maximum forward gain (S₂₁) of 5.2 dB while drawing 23 mW from a 1.8-V supply. A noise figure as low as 4.7 dB and an P-1dB of 4 dBm have been demonstrated
