Abstract
An analog-to-digital converter (ADC) comprises a sample/hold (S/H) unit, a digital-to-analog converter (DAC), a comparing unit, and a control unit. The S/H unit samples a first analog signal. The control unit comprises a compensating unit. The compensating unit receives an indication signal, and compensates a current bit and all its less significant bits, such that the sum of the current bit and all its less significant bits approximates a bit weight of the current bit, when the indication signal indicates that the comparison result cannot be determined. The compensating unit then outputs the compensated current bit and all its less significant bits together with more significant bits of the current bit.
