Abstract
Multiphase voltage regulator systems are disclosed which include parallel signal pathways that functionally cooperate to provide an analog output signal at a constant, 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 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 to lessen this difference or error. In some situations, manufacturing variations and/or misalignment tolerances present within the parallel signal pathways can cause mismatches between the parallel signal pathways. In these situations, the parallel signal pathways compare remaining energy storage element charging signals to the gl…
