Abstract
A mixed-signal integrated circuit (IC), including: a voltage booster that includes one or more charge pump devices configured to receive an input voltage, an oscillator signal, and a control signal, wherein the one or more charge pump devices comprise a network of capacitors switchable to provide a charged pumped in response to the control signal, and wherein the one or more charge pump devices, using the pumped, generate a boosted voltage based on the input voltage and at least a portion of an amplitude of the oscillator signal, a voltage regulator coupled to the one or more charge pump devices and configured to receive the boosted voltage and generate a regulated boosted voltage based on the boosted voltage, and a control and monitoring engine configured to provide the control signal based on, at least in part, the input voltage, the oscillator signal, and the regulated boosted voltage.
