Patent ID: 7417605

Claim:
An electronic circuit, comprising: a first circuit unit including a plurality of transistors through which a first current having a first current level passes; a switching element mutually connected to the plurality of transistors in the first circuit unit; a capacitor element to store a quantity of electric charge corresponding to the first current level; and a second circuit unit including a plurality of transistors to generate a second current having a second current level different from the first current level on the basis of the quantity of electric charge stored in the capacitor element, respective gates of the plurality of transistors in the first circuit unit being mutually connected to respective gates of the plurality of transistors in the second circuit unit, the plurality of transistors in the first circuit unit and the plurality of transistors in the second circuit unit having the same driving capability, the first circuit unit and the second circuit unit constituting a current mirror circuit through the capacitor element by turning on the switching element, and the plurality of transistors in the first circuit unit are connected in one of series or parallel and the plurality of transistors in the second circuit unit are connected in the other one of series or parallel.
