Abstract
A self-calibration system includes a variable current source to generate a default source current for charging a capacitive load, and a load charge calibrator to detect a voltage associated with the capacitive load when charged by the default source current, and to generate a current control feedback according to the detected voltage and a desired charged voltage of the capacitive load, the current control feedback to indicate to the variable current source a charge current capable of charging the capacitive load to the desired charged voltage.
