とする半波整流回路。 In an emitter follower circuit, the collectors and emitters of two transistors are connected together, a resistor is connected to the emitter, and an appropriate positive and negative voltage bias is applied between the resistor connected to the emitter and the collector. A capacitor is connected to the base of one of the transistors, and an electrical alternating current signal is applied to the base of the one transistor through the capacitor, and a DC bias is applied to the bases of the two transistors through resistors. The circuit is configured as follows, and is characterized in that a forward voltage of a diode is used to match the DC bias value with the VBE voltage of the transistor, and a half-wave rectified signal of the AC signal is obtained between the emitter and ground. Half-wave rectifier circuit.
