Abstract
Circuits and methods that enable a charge pump to provide sufficient charge to the gate of a switch NFET to turn the NFET ON within a specified switching time requirement but with minimal generation of electronic noise. An embodiment includes a dual-oscillator circuit configured to output from a first oscillator a first frequency signal from a first oscillator during normal operation, and to output from a second oscillator a second frequency signal higher in frequency than the first frequency signal for a selected time determined by a counter. An embodiment includes a charge pump coupled to the dual-oscillator circuit and configured to output an electrical charge as a function of an applied frequency signal from the dual-oscillator circuit, wherein application of the second frequency signal output during counting increases the amount of electrical charge output by the charge pump.
