ADAPTIVE EQUALIZER AND METHOD OF CONTROLLING THE SAME
First Claim
Patent Images
1. An adaptive equalizer comprising:
- an equalizing unit configured to equalize an input signal based on an equalization coefficient;
a plurality of sampling units configured to, generate a plurality of adjusted signals from the equalized input signal, each of the plurality of sampling circuits having a sensitivity that varies independently, and the plurality of sampling units configured to sample a respective one of the plurality of adjusted signals; and
an error detection unit configured to vary the equalization coefficient based on the sampled signals until an error is not present between the sampled signals.

Abstract
Provided are an adaptive equalizer for adaptively controlling an equalization coefficient until two comparators outputs a same value, after generating a sensitivity difference between signals at a front end of each comparator for performing sampling, and a method of controlling the adaptive equalizer.
