RECEIVER DEVICE AND REMOTE CONTROL SYSTEM

摘要

The disclosed receiver device (1) is equipped with a rectifying unit (10) which is provided with rectifying elements (Q9 and Q10) for rectifying a received signal that has been input; bias supply units (Q1 to Q8, C1 to C4, 14, and 15) for supplying a bias voltage (V) corresponding to the threshold voltage of the rectifying elements intermittently to the rectifying elements; detection units (12, 132, and 133) for detecting the presence or absence of the received signal on the basis of the output of the rectifying unit; and a control unit (131) for stopping the supply of the bias voltage when the detection units detect the received signal.
