Abstract
An oscillator circuit generates a constant delay time by use of a current source and a load element to determine a frequency of a clock. The oscillator circuit includes an integrator which integrates the clock, a first comparator which compares an output voltage of the integrator with a reference voltage, and a variable current source which changes a current in accordance with the comparison result of the first comparator. The frequency is corrected in accordance with the current of the variable current source.
