A 50–20 Gb/s, 80 mW Photonic Receiver With 59–70 dBΩ Gain and 12.3–8.2 pA/√Hz Input-Referred Noise

This letter presents the design and measurements of a monolithically integrated photonic receiver manufactured in 0.25 $\mu \text{m}$ SiGe BiCMOS electro-photonic technology. The receiver consists of an on-chip germanium photodiode directly connected to the transimpedance amplifier (TIA). An on-chip, low-noise feedback loop compensates the dc photocurrent. The circuit provides a maximum bandwidt...
