デイテクタ。 A pair of sample and hold voltages of a capacitor that sample and hold an input pulse signal through an operational amplifier and a diode are fed back to the operational amplifier through a voltage follower integrated with the operational amplifier and the diode. A peak peak circuit is constructed by connecting hold circuits in a dependent manner, and the capacitance of the capacitor in the previous stage is small and the capacitance of the capacitor in the next stage is larger.
Detector.
