PURPOSE:To obtain a peak detecting circuit for wave-detecting high frequency signals in stable manner. CONSTITUTION:As for a comparator 2, a signal line 1 is connected with one minus input terminal and the base of a PNP transistor 3 is connected with an output terminal. The emitter of the PNP transistor 3 is connected with a plus power source 6, and a condenser 9 is connected between the collector and the emitter, and the collector of the PNP transistor 3, grounded resistor 7, and other condenser 8 are connected with the other input terminal of the comparator 2. |
