ABSTRACT:
A semiconductor circuit device includes an oscillator for outputting an oscillating signal, a driving signal generator for generating driving signals having respective phases based on a counting of oscillations of the oscillating signal, and a charge pump circuit driven by the driving signals. A pulse width ratio of the driving signals to one another is constant even when an oscillation period of the oscillating signal output by the oscillator changes, whereby the charge pump operates properly under changing conditions.
