Abstract
A data receiver includes group envelope detection circuitry that produces a group envelope voltage. The group envelope voltage represents the average envelope of a plurality of amplified data signals. Associated feedback adjusts the gains applied to each data signal to minimize any difference between the group envelope voltage and a reference voltage. The reference voltage is preferably the envelope of a clock signal associated with the data signals.
