An 8Gb/s Capacitive-Coupled Receiver with High Common-Mode Rejection for Un-Coded Data This publication appears in: IEEE JOURNAL OF SOLID-STATE CIRCUITS Authors: X. Maillard and M. Kuijk Volume: 39 Issue: 11 Pages: 1909-1915 Publication Date: Nov. 2004
Abstract: An 8-Gb/s receiver is demonstrated in 0.35-mum SiGe with two on-chip 60-fF ac-coupling capacitors. These capacitors are formed by on-chip metal layers and have a breakdown voltage of at least +/뉺 V, which is the dc input range of the receiver. The receiver especially resists strong ac common-mode edges with a slew rate up to 4 V/ns for enhanced EMI rejection. The self-clocked quantized feedback technique used, features uncoded data that contains long sequences of consecutive identical digits or ac-unbalanced data. The differential input sensitivity is 0.5ǃ.1 Vpp with a supply voltage between 2.5 and 3.5 V
