A 42.7Gb/s Optical Receiver With Digital Clock and Data Recovery in 28nm CMOS

This paper presents a broadband optical receiver that employs multiple bandwidth extension techniques in analog front-end (AFE) and has efficient digital clock and data recovery (CDR). The AFE is implemented exclusively with inverter-based stages. It consists of a shunt feedback transimpedance ampli...
