Abstract
A dual loop regulator is configured for improved regulation of a supply voltage for a dynamic load based on the magnitude of changes in the load voltage. An exemplary dual loop regulator comprises a primary voltage regulator configured within a linear loop and a secondary voltage regulator configured within a wideband, non-linear loop. The primary voltage regulator is configured for providing a well-controlled, regulated output voltage to the dynamic load, and for addressing small changes in the output voltage. The secondary voltage regulator is configured for sensing undervoltage and overvoltage conditions at the dynamic load, and for addressing changes greater than a predetermined threshold voltage. To facilitate loop stability, secondary voltage regulator can be configured within the wideband, non-linear loop to have a small gain for small changes, a larger gain for large changes, and/or a substantially finite storage capability such that any large signal oscillations will not be sustained.
