Abstract
A high-speed optical interface circuit for 850-nm op-
tical communication is presented. Photodetector, transimpedance
amplifier (TIA), and post-amplifier are integrated in a standard
0.18-
m 1.8-V CMOS technology. To eliminate the slow substrate
carriers, a differential n-well diode topology is used. Device simu-
lations clarify the speed advantage of the proposed diode topology
compared to other topologies, but also demonstrate the speed–re-
sponsivity tradeoff. Due to the lower responsivity, a v
