  • Out-of-calibration circuits and methods and systems using the same
    Patent number: 6316991
    Abstract: A voltage out-of-calibration detector 200 includes a voltage divider operating between first and second voltage rails and having a plurality of taps 203 for generating first and second comparison voltages. A first set of switches 205 selectively couples at least one of the plurality of taps 203 to the input of a first voltage comparator 401a, first voltage comparator 401a comparing the first comparison voltage with an input voltage and outputing a signal when the input voltage exceeds the first comparison voltage. A second set of switches 206 selectively couples at least one of the plurality of taps 203 to an input of a second voltage comparator 401b, second voltage comparator 401b comparing the second comparison voltage with the input voltage and outputing a signal when the input voltage is below the second comparison voltage. Control logic 300 selectively activates the first and second sets of switches 205/206 in response to received control signals.
