Abstract
An active digital voltage regulator circuit is a two terminal device that is connected in shunt to first and second power supply input lines. The active digital voltage regulator circuit stores energy during times when the local power supply voltage is greater than a predefined voltage, e.g., during times when the parasitic inductances supplement the local power supply voltage. A control circuit within the regulator circuit is a combination of two self-biasing and off-set nulling power supply monitor circuits. Each power supply monitor circuit further includes a differencing, non-overlapped, dual-output amplifier connected to the first and second power supply input lines. The differencing, non-overlapped, dual-output amplifier includes a predriver stage and an output stage, both of which are connected to the first and second power supply input lines.
