PROBLEM TO BE SOLVED: To generate a voltage of a sufficient level as a predetermined voltage to be necessary by receiving an AC signal by electromagnetic induction, rectifying its signal, boosting the rectified signal, and smoothing the boosted signal. SOLUTION: The voltage generator circuit 100 comprises a coil 11 and a capacitor 12 for constituting a receiving circuit, four diodes 13 to 15 of rectifiers connected in a bridge for constituting a rectifier circuit 30, three diodes 18 to 20 and capacitors 21, 22 of capacity elements forward connected for constituting a booster, and a capacitor 22 for constituting a smoothing circuit. Thus, the generator circuit 100 can boost a voltage of the signal of an output of the circuit 100 by providing the booster. Accordingly, a distance between the coil 11 of circuit 100 and a coil of an external unit is separated, and hence even if an amplitude of the AC signal generated from the coil 11 is low, a sufficient level can be assured as the output of the circuit 100. |
