High speed and low power silicon-based receiver front-end for optical interconnect

We demonstrate an optical receiver front-end using a CMOS TIA with a germanium-on-silicon PD. The amplifier only occupies 0.09 mm
²
with 12 mW power consumption, and achieves a 27.5 GHz 3-dB bandwidth. The integrated silicon-based receiver shows well opened eye diagrams up to 20 Gb/s.
