ABSTRACT:
An analog to digital converter comprising a reference signal generator, a comparator, and a counter wherein the reference signal generator is operable to generate a reference for converting an analog signal into a digital signal. The reference signal generator is also operable to generate a plurality of the reference signals based on the change in a voltage. The comparator is operable to compare the analog signal with the reference signal generated by the reference signal generator. The counter is operable to count, in parallel with a comparison performed by the comparator, a predetermined count clock and to hold a count value at the time of completion of the comparison.
