Abstract
A system and method have been provided for selectably equalizing an input signal to an integrated circuit (IC), to compensate for degradation in the transmission process. The selectable equalization circuit includes parallel equalizing and non-equalizing sections. When the equalizing section is engaged a resonant element modifies the circuit impedance to add a zero to the circuit transfer function. When the non-equalizing function is engaged, the equalizing section is disengaged without degrading gate capacitance, and the input signals are processed without a zero in the transfer function.
