  • Double differential comparator and programmable analog block architecture using same
    Patent number: 6701340
    Abstract: A double differential comparator can be efficiently implemented utilizing a first comparator stage having a folded cascode with floating gate input terminals and clamped single-ended output, and a capacitively coupled input stage for transferring a weighted sum of input signals to the floating gates of the first comparator stage. Additionally, the double differential comparator can be integrated into fully differential programmable analog integrated circuits. Such fully differential programmable analog integrated circuits can also include a differential output digital-to-analog converter to be used with or without the double differential comparator.
