ABSTRACT:
A start signal detection circuit includes a wave-detection circuit1outputting a voltage in accordance with an envelope of a radio signal from an output point B, a reference voltage generation circuit2outputting a voltage at the output point B at a non-signal state as a reference voltage to a reference point C, and a differential amplification circuit3amplifying and outputting a voltage difference between the output point B and the reference point C.
