ABSTRACT:
The charge pump circuit includes: a first switch for controlling either one of push operation and pull operation based on a first control signal; a current mirror circuit composed of a transistor different in attribute from the first switch; and a second switch composed of a transistor same in characteristic as a transistor constituting the first switch, for controlling input of a current into the current mirror circuit based on a second control. The other operation, the push operation or the pull operation, is performed with a current output from the current mirror circuit.
