ABSTRACT:
An object is to provide a circuit configuration with which the number of transistors can be reduced and power conversion efficiency can be prevented from being reduced, in a transmitting and receiving circuit. The transmitting and receiving circuit includes a voltage doubler rectifier circuit having N stages, each of which includes a capacitor, where N is a positive integer. The voltage doubler rectifier circuit having N stages is connected to a circuit having a modulation function. In the capacitor in any one of the N stages, one electrode of the one capacitor is connected to an input terminal of the transmitting and receiving circuit, and a node to which the other electrode of the one capacitor is connected is connected to a circuit having a demodulation function. Since the transmitting and receiving circuit can be formed of fewer transistors, it can be reduced in size. Since a reduction in power conversion efficiency can be prevented, a power supply potential can be efficiently generated.
