Abstract
A 50 dB-Ω transimpedance amplifier (TIA) with a bandwidth greater than 110 GHz has been demonstrated using InP HBT technology. The wide-band amplifier with a cutoff frequency > 110 GHz was designed and fabricated in HRL Laboratories´ G4 0.25 μm InP HBT IC technology. The amplifier operates at -4.0 V with a current draw of 76 mA for a power consumption of 304 mW. The basic Cherry-Hooper gain cell is used with a single-ended input and a differential output buffer stage.
