Abstract:
A discharge circuit includes: a first transistor connected to power storage; an operational amplifier for controlling an output current of the first transistor; and the current mirror circuit connected to the operational amplifier. The current mirror circuit includes a second transistor connected to a non-inverting input terminal of the operational amplifier, and a third transistor connected to the power storage.
