A 20Gbps 1.2GHz Full-Duplex Integrated AFE in 28nm CMOS for Copper Access

© 2017 IEEE. A 28nm CMOS 1.2GHz full-duplex analog front end (AFE) is presented. The AFE can deliver 20Gbps of aggregate service across 50m of RG6 coax. The on-chip line driver, powered from a 7.2V supply and using core transistors, delivers 5.9V ptp differential to the line through the hybrid. A tu...

description © 2017 IEEE. A 28nm CMOS 1.2GHz full-duplex analog front end (AFE) is presented. The AFE can deliver 20Gbps of aggregate service across 50m of RG6 coax. The on-chip line driver, powered from a 7.2V supply and using core transistors, delivers 5.9V ptp differential to the line through the hybrid. A tunable capacitive hybrid circuit for full duplex operation is proposed for low noise performance and allows channel matching. A cancellation of 23.1dB on average is achieved across the full band. A 3-stage receiver with input over-voltage protection is capable of driving 50Ω differential loads. The chip occupies 0.28mm 2 of active area and consumes 1.53W.
