Adaptive equalizer with DC offset compensation

摘要

A method for correcting DC offsets in a multi-stage amplifier includes determining (806, 808) a DC offset imparted by a multi-stage amplifier to an input signal. The method further includes applying a correction voltage (802, 804, 810, 812) to a plurality of selected stages in the multi-stage amplifier. The total correction voltage applied substantially negates the DC offset imparted by the multi-stage amplifier.
