Optical transimpedance receivers implemented in CMOS VLSI technologies are modeled and optimized for free-space optoelectronic interconnections. Sensitivity, bandwidth, power dissipation, and circuit area are analyzed for receivers using three different submicron CMOS processes. A comparison with the circuit noise limited optical power indicates that, for digital computing applications, the receiver sensitivity is limited by the gain-bandwidth product of the receiver amplifiers and the necessary noise margin of logic circuits.
