Abstract :
A high speed, low noise 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. This preamplifier has a power gain S21 of 22 dB with the bandwidth of 6GHz, and can operate at 10 Gb/s with dynamic range from 2.5/spl mu/A up to 2.5 mA. The power consumption is only 88 mW.
