| Summary: | B T CONTThere is provided a sensor threshold circuit that makes available a hysteresis width that is not dependent on the change in a threshold point. Since a bias current Iis generated by a threshold current Iand a threshold adjusting current I, the threshold point is given by a coefficient A and a coefficient K and the hysteresis width |BH| is given by the coefficient K. Accordingly, when the coefficient K is determined, the hysteresis width |BH| is not dependent on the coefficient A and keeps a constant value. In addition, since the coefficient A depends on the resistance ratio, the threshold point is variable by changing a single resistor. Further, when the coefficient K is determined, the hysteresis width |BH| is also determined to be a single value with no variations in its value, no changes according to temperature, and no changes over time. |
