摘要
Dynamic error quantizer tuning systems and methods prevent misconvergence to local minima by using a dynamic quantizer circuit that controls reference voltages from three or more comparators that are independently adjusted to modify the transfer function of the dynamic quantizer circuit. A weighted sum of the comparator outputs is subtracted from the input to form an error signal in a control loop. The ratio of the reference voltages is chosen to reduce or eliminate local minima during convergence of the control loop and is set to values that minimize a root mean square error signal with respect to discrete modulation states of the input after the convergence of the control loop is complete.
