High bandwidth transimpedance amplifier design using active transmission lines

چکیده
A transimpedance amplifier (TIA) is designed based on the first order wave equation. The feedback resistance is set as the ohJective function for transimpedance. The main feedback amplifier provides transimpedance and a wide band compensation amplifier determines the characteristics of overall TIA. The stability of lhe T lA 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 ym standard CMOS process.
