510 Gbs 70 mW Burst Mode AC Coupled Receiver in 90-nm CMOS Masum Hossain and Ant

Abstract

ct—A low power burst mode receiver architecture is pre- sented which can be used for AC coupled links where low frequency signal components are attenuated by the channel. The nonlinear path comprises a hysteresis latch that recovers the missing low fre- quency content and a linear path that boosts the high frequency component by taking advantage of the high pass channel response. By optimally combining them, the front-end recovers NRZ signals up to 13 Gb/s burning only 26 mW in 90 nm CMOS. A low
