Inventor: KINDER RUSSELL
IPC: G05F1/56
Filed: 2018-09-27
Abstract: Disclosed is a multiphase voltage regulator system which includes parallel signal pathways that functionally cooperate to provide an analog output signal at a constant voltage or substantially constant voltage. The parallel signal pathways generate energy storage element charging signals to charge and/or discharge energy storage elements. Energy provided by discharging the energy storage elements is thereafter combined to provide the analog output signal. Moreover, the parallel signal pathways compare one of the energy storage element charging signals with a reference input signal to provide a global error correction signal representing a difference or error between the reference input signal and the analog output signal. The parallel signal pathways thereafter adjust the energy storage element charging signals in accordance with the global error correction signal in order to lessen the difference or error. In some situations, manufacturing variations and/or misalignment tolerances present within the parallel signal pathways may cause mismatches between the parallel signal pathways. Then, the parallel signal pathways compare remaining energy storage element charging signals to the global error correction signal to provide local error correction signals, thereby quantifying the mismatches. Thereafter, the parallel signal pathways adjust the remaining energy storage element charging signals in accordance with the one or more local error correction signals in order to compensate for the mismatches.
