Abstract

An 8-Gb/s receiver is demonstrated in 0.35-μm 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 ±690 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 4V/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 0.5-1.1Vpp with a supply voltage between 2.5 and 3.5 V.
