A 24mW 1.25Gb/s 13k/spl Omega/ transimpedance amplifier using active compensation

A transimpedance amplifier using active compensation is demonstrated to achieve 3X bandwidth enhancement in a 0.35μm CMOS technology. At a BER of 10
¹²
, the measured dynamic range is -29.5 to 0dBm at 1.25Gb/s. The differential transimpedance gain is adjustable from 500Ω to 13kΩ. The IC consumes 24mW from a 3V supply
