Abstract

PURPOSE:To obtain a constant unchanged hysteresis characteristic by partially voltage-dividing an unchanged output voltage, and obtaining a threshold. CONSTITUTION:A voltage comparator A inputs one side input voltage V11 to an inversion input terminal, inputs other side input voltage to a non-inversion input terminal through an input impedance Z1 and an output voltage is inputted to an amplifier B. The output terminal of the amplifier B is connected through a feedback impedance Z2 to the non-inversion input terminal of the voltage comparator A. Even when the output voltage of the voltage comparator A is smoothly changed, a hysteresis characteristic to occur at an output voltage VOUT of the amplifier B shows the steep change. Thus, a voltage gain is increased, the output voltage is fed back and the threshold voltage is formed. Thus, the hysteresis width can be always constantly held.
