ABSTRACT:
An electric circuit device operable under a power supply includes: a circuit; a first switch connected between the power supply and the circuit; a capacitor tending to produce a first leakage current; a second switch connected between the power supply and the capacitor, the second switch producing a second leakage current when it is cut off, the second leakage current being less than the first leakage current; and a switch controller for turning on the second switch while both the first switch and the second switch are turned off, and after a first time passes for turning on the first switch.
