Abstract
A receiving device is provided capable of avoiding reception of unnecessary energy when a signal waveform actually changes on a receiving side. An impedance control circuit includes a sensing unit to sense one or more of a voltage, current, or power of a signal to be received by a receiving circuit. The impedance control unit varies an input impedance according to the change in the sensed one or more quantities so that the received signal will be reflected. Thus the excess energy of the signal is reflected and fed to any other receiving circuit achieving stable communications.
