ABSTRACT:
A voltage to pulse-width conversion circuit having counter which counts a reference frequency and produces a digital output signal having a multi-bit digital value; a decoder which decode the multi-bit digital value of the digital output signal and outputs first and second decoded signals; a digital/analog converter which receives the first and second decoded signals and produces an analog signal having an analog voltage; a comparator which compares the reference voltage and the analog voltage and produces a comparison result signal and a setting circuit which sets the level of the output node to a predetermined voltage level in response to the first and second decoded signals.
