Abstract

A charge pump voltage regulating circuit which uses a constant current generator and a second current generator, controlled by the output voltage of the charge pump circuit. The current from the constant current generator is divided between the input to a current controlled oscillator and the second current generator. When the output voltage of the charge pump circuit increases the current in the second current generator increases, the current flowing into the current controlled oscillator decreases, the frequency of the clock signals supplied to the charge pump circuit decreases, and the output voltage of the charge pump circuit decreases. When the output voltage of the charge pump circuit decreases the current in the second current generator decreases, the current flowing into the current controlled oscillator increases, the frequency of the clock signals supplied to the charge pump circuit increases, and the output voltage of the charge pump circuit increases.
