Abstract :
This paper presents a fully-differential CMOS front-end amplifier using gm-boosting and noise-canceling techniques. The proposed front-end amplifier is designed based on a 0.18 μm standard CMOS process and 2 V supply. Simulation results show noise figure (NF) of 2.9 dB, while the voltage gain and bandwidth of the amplifier are 31.6 dB and 2 GHz, respectively. The power dissipation is 19 mW.
