This work investigates the feasibility of the integration of interface circuits for op- tical communication systems in a standard unmodified digital CMOS process. This paves the way for single chip communication systems where the optical interfaces are integrated on the same die as the required digital circuitry. The optical receiver is a key element in the optical communication link. In this work, a transimpedance amplifier, which consists of a voltage amplifier with resis- tive feedback, is used as the first stage. Unlike for many other circuits, the optimal place of its dominant pole is...
