  • Comparator and analog-to-digital converter
    Patent number: 6624667
    Abstract: A comparator for an analog-to-digital converter having a tri-state inverter provided on the side where an input of a data register section is located, wherein the need for a switch on the input side in the data register section is eliminated to allow reduction of the number of components used in a comparator, and the flow-through current of the tri-state inverter can be reduced significantly by operating the tri-state inverter as a common inverter after making outputs from the comparator stable.
    Type: Grant
