This paper presents a depletion InAlAs/InGaAs HEMT-based single supply transimpedance amplifier circuit for optical communication receiver. It is composed of an amplifier stage, two stages of source follower, an output stage and a feedback resistance. The schemes of single supply voltage, single-ended input and differential output are adopted in the circuit. While operating at 2.5 Gbit/s, the preamplifier shows a transimpedance of 62.5 dbΩ. The chip consumes 272 mW at a single + 5 V supply voltage.
