Abstract

A transimpedance amplifier with differential DC-coupled photocurrent sensing was integrated in a standard 0.35 /spl mu/m CMOS process. It achieves 33 k/spl Omega/ transimpedance gain and a bandwidth of 255 MHz with a 2 pF photodiode capacitance. This design exhibits 40 dB power supply rejection ratio and an average input noise of (6.8pA)/(/spl radic/Hz). Power dissipation is 30 mW from a 3 V supply.
