Abstract :
This paper describes a low power optical receiver for discrete photodiodes. The receiver utilizes an input stage bandwidth of only 2GHz, affording high gain with low power consumption while limiting input-referred noise. The resulting ISI is eliminated and data recovered using an IIR DFE. The IIR DFE utilizes a local feedback to relax the timing criteria of the DFE loop. The 65-nm CMOS chip consumes 14.7 mW at 19.6Gbps.
