Abstract
By using a first delay circuit that delays by a predetermined time a reference pulse signal having a constant pulse width and a second delay circuit that delays by an arbitrary time the output signal of the first delay circuit, a voltage conversion circuit generates an output pulse signal having a variable pulse period, and varies its output voltage according to the pulse period of this output pulse signal.
