Abstract :
A cable equalizer for 10Gb/s broadband data using a SiGe BiCMOS process is presented. The circuit consists of a feedforward amplifier with a variable peaked that compensates for a copper cable of length up to 3 feet, and a feedback circuit that detects the data transition times and generates an appropriate control voltage. The detector makes use of a novel circuit based on the source-coupled node of a differential pair.
