Scaled signal processing elements for reduced filter tap noise

A decision feedback equalizer, comprising:

• a summer configured to receive an input signal and at least one data response signal and to output an output signal based, at least in part, on the at least one data response signal;
• a signal processing unit configured to receive the output signal, wherein the signal processing unit is further configured to generate a data signal and at least one coefficient signal based, at least in part, on the output signal;
• dynamic gain logic coupled to the signal processing unit and configured to receive the at least one coefficient signal, wherein the dynamic gain logic is further configured to generate at least one gain signal based, at least in part, on the at least one coefficient signal;
• a transversal filter coupled to the signal processing unit and configured to receive the data signal and the at least one coefficient signal, wherein the transversal filter is further coupled to the dynamic gain logic and further configured to receive the at least one gain signal, wherein the transversal filter is further configured to generate the at least one data response signal based on a product of a coefficient corresponding to the at least one coefficient signal and a gain corresponding to the at least one gain signal.

A method for generating an output signal, the method comprising:

• providing, using an error estimator, an error estimate signal;
• providing, using a coefficient generator, a first control signal based, at least in part, on the error estimate signal;
• providing, using dynamic gain logic, a second control signal based, at least in part, on the first control signal;
• determining at least one coefficient value and at least one multiplier value based, at least in part, on the first control signal and the second control signal, respectively;
• generating at least one weighted value based, at least in part, on a product of the at least one coefficient value and the at least one multiplier value;
• and
• providing an output signal based, at least in part, on an input signal and the at least one weighted value.
