High bandwidth transimpedance amplifier design using active transmission lines

A transimpedance amplifier (TIA) is designed based on the first order wave equation. The feedback resistance is set as the objective function for transimpedance. The main feedback amplifier provides transimpedance and a wide band compensation amplifier determines the characteristics of overall TIA. The stability of the TIA is not affected due to the open loop nature of compensation. Simulation results show that the TIA achieves a 58 dB gain and 1.32 GHz bandwidth in a 0.25 /spl mu/m standard CMOS process.
