′[Claims for Utility Model Registration] A transistor whose operating point is set so that the current between the collector and emitter is almost cut off is used as a detector, and the input signal applied to the base of the transistor and the detected output are detected by the input signal applied to the base of the transistor. In the detection circuit, a bias voltage is applied to the base of the trasilister through a diode so that the input signal is extracted from a resistor inserted in a current path including an emitter, and the input signal is connected to the A detection circuit characterized in that the detection circuit is supplied between a base of a transistor and the diode.
