Abstract
A self-calibrating, adaptive equalization system for generating an ideal digital signal is disclosed. The adaptive equalization system includes an equalizer and a high-gain buffer. The equalizer includes a first equalizer loop that feeds-back a control voltage to the equalizer and the high-gain buffer that includes a second equalizer loop that feeds-back a high-pass-to-low-pass filter ratio signal. Each of the first and second equalizer loops has a high-pass and a low-pass filter, rectifying circuits for each of the filters, and an integrating circuit that compares signal energy output from the rectifiers. The adaptive equalization system generates an ideal digital signal.
