Abstract
Demodulator includes reception quality evaluation circuit for evaluating the quality of a received signal by comparison with a first reference value, and outputting an evaluation signal; and driving circuit receiving the evaluation signal. If reception quality evaluation circuit evaluates that the quality of the received signal is acceptable, power supply from driving circuit to DC offset control loop is stopped. This offers a high-frequency receiver that reduces power consumption.
