Abstract
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.
