ABSTRACT:
An electronic apparatus is comprised of a generator 11 in which a voltage is changed as time elapses, a booster circuit 12 for boosting an output voltage of the generator 11, and an oscillator circuit 13 that drives the booster circuit 12. When the voltage of the generator 11 changes as time elapses so that the voltage exceeds the minimum driving voltage of the oscillator circuit 13, the oscillator circuit 13 obtains power for starting oscillation from the generator 11. The oscillator circuit 13 that has started oscillation drives the booster circuit 12 to thereby boost the output voltage generated by the generator 11. Since the oscillator circuit 13 after starting oscillation continuously performs oscillation using the power boosted by the booster circuit 12, even if the voltage of the generator 11 changes as time elapses so that the voltage becomes lower than the minimum driving voltage of the oscillator circuit 13, the voltage can be boosted to the minimum driving voltage of the oscillator circuit 13 or higher.
