準電圧パルス発生回路。 An operational amplifier whose output is fed back to the inverting input terminal via a diode for reverse current blocking, a reference voltage source connected to the non-inverting input terminal of the operational amplifier, and a reference voltage source connected to the output terminal of the operational amplifier when the diode is reverse biased. A reference voltage pulse generation circuit comprising: a reference voltage source that provides a voltage different from that during bias; and a switch connected to a non-inverting input terminal of an operational amplifier and switching the bias direction of the diode by turning on and off.
