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.

Abstract: A system is provided for supplying current to a dynamic load subject to transient current requirements. A sense unit coupled to the dynamic load is configured to sense the rate of change of supply current required by the dynamic load during a transient event. A current source coupled to the sense unit is configured to supply a current pulse to the dynamic load in response to the sense unit determining that the rate of change of supply current (di/dt) exceeds a predetermined threshold. The current pulse preferably has a shape characterized by a first region and a second region subsequent to the second region, wherein the first region includes a first boost current which exceeds the transient current requirement, and wherein the second region includes a second boost current which is less than the transient current requirement. More generally, a wideband transient suppression system is provided for controlling a wide spectrum of transients. The wideband system includes a primary regulator configured to compensate for low frequency transients, and a secondary regulator configured to provide short-term compensation current to the dynamic load until the relatively slow primary regulator can accommodate the transient event. The secondary regulator includes two major functional blocks: a close-loop voltage-sensing compensation circuit configured to compensate for transients falling within a mid-range frequency range, and an open-loop di/dt-sensing compensation circuit configured to compensate for transients falling within a high-frequency range.
