Abstract :
A fully differential transimpedance amplifier has been designed and implemented in 0.18 μm standard digital CMOS technology. The parallel feedback circuit topology is adopted to broaden the bandwidth. It can operate at 10 Gbit/s with the dynamic range from 25 μA up to 2.5 mA. The power consumption is only 88 mW under 2 V supply voltage.
