  • Latched comparator and methods therefor
    Patent number: 8143921
    Abstract: A compare cycle of a comparator includes a precharge phase and a compare phase. During the precharge phase, a node of the comparator is precharged to a defined voltage. In addition, during the precharge phase an input transistor of the comparator is decoupled from the node. During the compare phase, an input voltage is coupled to the node via the input transistor. The input transistor is maintained in saturation during both the precharge phase and the compare phase, reducing switching noise.
    Type: Grant
    Filed: August 3, 2009
    Date of Patent: March 27, 2012
    Assignee: Freescale Semiconductor, Inc.
    Inventors: Fernando Z. Neto, Fernando Chavez Porras, Jon S. Choy, Walter Luis L. Tercariol
