  • Differential hysteresis comparator circuits and methods
    Patent number: 8570072
    Abstract: A comparator circuit for providing hysteresis comprises first and second differentially coupled transistors. The first of the differentially coupled transistors provides drain current to first and second load transistors. The second of the differentially coupled transistors provides drain current to third and fourth load transistors. In one example embodiment, the drain of the first of the differentially coupled transistors also drives the gate of the first and third load transistors, while the drain of the second of the differentially coupled transistors drives the gate of the second and fourth transistors.
    Type: Grant
    Filed: November 2, 2010
    Date of Patent: October 29, 2013
    Assignee: Marvell International Ltd.
