摘要： A wideband voltage regulator is configured to provide suppression of fast transients, which can include a boosting circuit and a sensing circuit. The boosting circuit can be suitably configured to boost the voltage regulator response, while the sensing circuit can determine when such a boost may be desired. Accordingly, the response of the voltage regulator can be accelerated to a fast load transient beyond the closed loop bandwidth limited response or the slew rate limited response of the voltage regulator. An exemplary voltage regulator can be configured with an active sensing circuit comprising a sensing amplifier with switch control outputs, and a boosting circuit comprising N stored charge sources, e.g.; boost capacitors, and (3N−1) switches that are configured to accelerate the voltage regulators response to a fast load transient beyond the closed loop bandwidth limited or slew rate limited response of the voltage regulator.

摘要： 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.

摘要： Methods and apparatus for a multiphase power regulator according various aspects of the present invention operate in conjunction with an active transient response (ATR) system for applying a correction signal to a multiphase pulse width modulator.
