Abstract
An adaptive CTLE used in a receiver with its zero and/or pole frequencies automatically and continuously adjustable based on an error signal and post-cursors. The error signal is derived from the sliced equalized signal that is output from the CTLE. A correction control signal can be determined based on one or more delayed and sampled data (corresponding to the post-cursors) and the error signal. As controlled by the correction control signal, the CTLE zero/pole frequency setting is then adapted such that the CTLE transfer function causes the error signal to decrease while the post cursor ISI is reduced or eliminated. As a result, effective equalization can be advantageously accomplished in a consistent and fast manner.
