Abstract
A monolithically integrated optoelectronic receiver based on the pseudomorphic InGaAs on GaAs material system has been fabricated and tested for the first time. Quarter-micrometer modulation-doped field-effect transistors (MODFETs) with f/sub t/'s of 66 GHz are used in the two-stage transimpedance amplifier design. The circuit utilizes all active components including a metal-semiconductor-metal (MSM) photodetector and a common-gate FET active feedback resistor. >
