  • Comparator with hysteresis
    Patent number: 5319265
    Abstract: A comparator with hysteresis in which a reference voltage of the comparator is easily adjustable. A resistor for dropping the reference voltage and a current source are coupled to a reference voltage terminal, and function to adjust the reference voltage in response to the level of an output voltage. Thus, the hysteresis voltage of the comparator can be easily adjusted by varying the current flowing through the resistor.
