A Large Bandwidth RGC Transimpedance Preamplifier is designed for amplifying the high-fideli-ty timing singal in Switch Capacitance Array chip application. This amplifier have characteristics of low input impedance, large bandwidth, high transimpedance. It will be made under TSMC 0.25μm CMOS technology, and the supply voltage is single 2.5V. Simulation results indicate: the transimpedance is 5000 ohm,-3dB BW is 953MHz, and the detector output capacitance have litter effect on the bandwidth in some range.
