Abstract
The present disclosure discloses an analog-to-digital conversion apparatus. A first stage conversion circuit receives an analog input signal to generate a digital conversion result. A second stage conversion circuit calculates an analog residue between the analog input signal and the digital conversion result and feeds a pseudo-noise to generate and amplify a feeding result to generate a digital residue for a gain calculation circuit to perform correlation calculation with the pseudo-noise to generate a compensation gain. A control circuit controls the first stage conversion circuit to operate according to output resolutions to establish a look-up table for a compensation gain generation circuit to look up to retrieve one of the interval gain values as a compensation gain value. An output calculation circuit compensates an added result of the digital conversion result and the pseudo-noise to further add a compensation result with the digital residue to generate a digital output signal.
