Abstract :
A high bandwidth, lo w power consumption, low noise front-end amplifier is designed based on standard 0. 18um SiGe BiCMOS process. This front-end amplifier consists of a high performance differential RGC TIA, a 3 stage post amplifier and a buffer. The single stage of post amplifier is Cherry-Hooper amplifier. The entire circuit is simulated by a commercial software Cadence. The bandwidth and the differential transimpedence of the front-end amplifier are 13.22GHz and 87.3dBΩ with the input-referred r ms noise current 1.71μA and the power consumption 38.6mW.
