<P>PROBLEM TO BE SOLVED: To provide a receiving device which can achieve low power consumption. <P>SOLUTION: A receiving device generates a local signal of the same frequency as a desired high-frequency signal, mixes the local signal with the high-frequency signal in a mixer circuit 11, and activates a part related to generation of received data when a DC offset voltage Vof of an output signal ϕ11 of the mixer circuit 11 exceeds a reference voltage. Therefore, as it is possible to activate the part related to the received data only when the desired high-frequency signal is transmitted, power consumption is smaller than that of prior arts. <P>COPYRIGHT: (C)2013,JPO&INPIT |
