A 30Gb/s 0.8pJ/b 14nm FinFET receiver data-path
The demand for energy-efficient I/O link transceivers operating at raw data-rates in the tens of Gb/s continues to fuel innovation in the field of wireline communication . Receiving equalizers under one pJ/b are sought for chip-to-chip and chip-to-module links designed to operate across short-reach copper channels. Standards such as CEI-28G-VSR suit chip-to-module communication at raw data rates up to 28Gb/s and 10-12dB insertion loss at Nyquist. Proprietary and open standards in the same speed range are being developed too for data and memory-centric systems co-designed with CPUs and GPUs and channels with insertion loss on the order of 20dB .
