Apparatus having programmable taps and method of using the same

A method, comprising:

• generating a plurality of tap weights based on a plurality of delayed signals using a weight generator;
• generating, using a tap controller, tap weight enabling signals corresponding to one or more of the tap weights if the corresponding tap weights are greater than a predetermined threshold value;
• and
• generating, using the tap controller, a set of bias factors based on corresponding tap weights of the plurality of tap weights.

An apparatus, comprising:

• a plurality of delay elements configured to delay a respective input signal and to output a respective delayed signal;
• a weight generator configured to generate a plurality of tap weights based on the delayed signals;
• a tap controller configured to (1) generate tap weight enabling signals corresponding to one or more of the tap weights based on a determination that the corresponding tap weights are greater than a predetermined threshold value, and (2) generate a set of bias factors, each of the bias factors of the set of bias factors being based on a corresponding tap weight of the plurality of tap weights;
• a summer configured to output a weighted signal based on the delayed signals, the tap weight enabling signals, the tap weights of the plurality of tap weights that correspond to the tap weight enabling signals, and the bias factors of the plurality of bias factors;
• an analog to digital converter configured to convert the weighted signal to a digital signal, the digital signal being a first input signal received by a first delay unit of the plurality of delay units;
• and
• an error generator configured to compare the weighted signal with the digital signal,
• wherein the weight generator is configured to change the tap weights of the plurality of tap weights based on an output of the error generator.
