| Abstract: | A fully differential transimpedance amplifier has been designed and implemented in 0.18 /spl mu/m 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 /spl mu/A up to 2.5 mA. The power consumption is only 88 mW under 2 V supply voltage. |
