PURPOSE:To provide a receiving circuit capable of reducing unnecessary power consumption with simple constitution. CONSTITUTION:This receiving circuit is provided with an active circuit 1 including an active element and processing a receiving signal, a detection circuit 2 for detecting the receiving state of a receiver and a bias control circuit 3 for controlling the bias of the circuit 1 so as to reduce the power supply of the circuit 1 when the circuit 2 detects the receiving state more than a prescribed value. The circuit 3 is constituted of one or more comparators for comparing an output from the circuit 2 with a prescribed reference value. |
