ABSTRACT:
A first current mirror circuit performs its normal operation when a first switch is turned on, and is constructed so that a period during which the first current mirror circuit can output a current is realized when the first switch is turned off. A second current mirror circuit is connected to the first current mirror circuit so that the output current of the first current mirror circuit is decreased by an output current of the second current mirror circuit. A current output of a transistor and a current output of the first current mirror circuit are connected and outputted as an output signal. The first switch and a second switch are controlled by the output signal or a signal formed by the output signal being passed through a buffer circuit.
