摘要:In one embodiment, the present invention includes a circuit for suppressingnoise with adaptive charge-pump regulation. The circuit comprises an oscillator circuit, acharge pump, an amplifier, a current mirror, and a filter. The charge-pump receives an

oscillating signal and provides an output voltage. The amplifier is responsive to theoutput voltage and a reference voltage and provides a control signal. The control signalalters a frequency of the oscillator and the output voltage is responsive to thisfrequency. The current mirror and filter suppress a noise component of the outputvoltage. The current mirror provides a supply current to a regulator loop. The regulatorloop is operable to generate a consistent regulator voltage. In this manner, the adaptivecharge-pump allows for a more consistent, noise free, regulator voltage.
