Abstract :
This paper describes an inductively peaked 5GHz novel CMOS voltage-current feed-back transimpedance amplifier using TSMC 0.18μm 5M2P 3V Digital CMOS process technology. The bandwidth of the amplifier was extended using the inductive peaking technique, and, simulation results indicated a a -3db bandwidth of around 4.7GHz with a transimpedance gain of 50dB ohms. The amplifier features wide input dynamic range with automatic gain control. The average output noise voltage spectral density was 5nV/sqrt(Hz) (with a peak of ≈9nV/sqrt(Hz)), while, the input referred noise current spectral density was below 80pA/sqrt(Hz) within the amplifier frequency band.
