Abstract :
A wide bandwidth, low power consumption transimpedance preamplifier has been designed and implemented in 0.18 μm standard digital CMOS technology. A circuit topology with two gain stages is used to provide increased open-loop gain compared to a single stage design, and greater close-loop stability than a three-stage amplifier. The preamplifier has a transimpedance of 56 dBΩ with the bandwidth of 2.5 GHz, and can operate at 2.5 Gb/s with the dynamic range from 15 μA up to 1.5 mA. The power consumption is only 15 mW using 1.8 V power supply.
