摘要： Various embodiments of the present invention include enabling, during a calibration phase, a counter to count one less than a number of clock periods associated with a determined offset. The counted number of the clock periods is stored in calibration memory. In a conversion phase, inverted outputs are loaded from the calibration memory to the counter, where the counter is enabled to count the clock periods to determine a digital equivalent value of an analog signal amplitude.
