Abstract
A duty ratio/voltage conversion circuit that converts the duty ratio of an input signal into voltage level and outputs the voltage level includes: an input terminal to which the input signal is input; a first CR integrating circuit that integrates the input signal; a load resistor a first end of which is connected to an output point of the first CR integrating circuit, and a second end of which is grounded; and an output terminal connected to the load resistor. The first CR integrating circuit includes a first pathway that has a first resistor, and a second pathway in which a phase inversion portion, a second resistor and a first capacitor are connected in series, and is a parallel circuit in which first and second ends of the first pathway are connected to first and second ends, respectively, of the second pathway.
