Method and apparatus for a digital non-linear loop control circuit

摘要

Described herein are methods and system for providing digital non-linear loop control. In one embodiment, system with digital non-linear loop control comprises a parameter control circuit configured to modify a signal based on a control signal, a processing circuit configured to process the signal, and a parameter measurement circuit configured to measure a parameter value of the signal. The system also comprises a digital non-linear control circuit configured to compare the measured parameter value with a desired parameter value, to determine a control signal value based on the comparison using a lookup table (LUT) that characterizes a non-linear control response of the system, and to output the control signal to the parameter control circuit based on the determined control signal value.
