CONTROL CIRCUIT AND METHOD

摘要

In accordance with an embodiment, a control circuit includes a multifunction current analysis circuit configured to receive a first current and connected to a charge pump circuit. An output of a charge pump is connected to an input of the multifunction current analysis circuit, and an oscillator control circuit has an input connected to an output of the multifunction current analysis circuit and to an input of the charge pump through an oscillator circuit. In accordance with another embodiment, a method for controlling a voltage of a semiconductor component is provided that includes generating a first current, a second current, and a third current from a charge pump output circuit and comparing the second current level with the third current level to generate a first comparison result. The first comparison result is used to control a frequency of an output signal of an oscillator circuit.
