Abstract
A magneto-resistive asymmetry compensation system includes a linearizer ( ) interposed in a data path and a control loop ( ). The control loop uses signal estimates from an interpolated timing response unit ( ) to derive a magneto-resistive asymmetry error. The error term is used to obtain a control scaling input to the linearizer. The linearizer functions to multiply the scaling multiple to the square of the input signal and then add it back to the input signal.
