  • Accurate, fast, and user programmable hysteretic comparator
    Patent number: 6229350
    Abstract: The present invention involves a hysteretic comparator (100) for comparing a sample voltage (VOUT) to a reference voltage (VREF). A hysteresis voltage generator providing a voltage VHYST− and a voltage VHYST+. A first differential input stage (505) generates a signal coupled to a summing node (506, 507) determined from a difference between the sample voltage and VREF. A second differential input stage (504) generates a signal coupled to the summing node determined from a positive difference between VHYST− and VHYST+. A third differential input stage (503) generates a signal coupled to the summing node determined from a negative difference between VHYST− and VHYST+. A control device (512, 513, 514) coupled to selectively enable the second and third differential input stages to select among a first mode and second mode.
