Abstract:
1. An analog-to-digital converter (ADC), comprising a sample/hold (S/H) unit, a digital-to-analog converter (DAC), a comparing unit, and a control unit, wherein the sample/hold unit is configured to sample a first analog signal; the digital-to-analog converter communicatively coupled to the control unit and configured to convert a feedback signal to a second analog signal; the comparing unit is communicatively coupled to both the sample/hold unit and the digital-to-analog converter, and configured to compare the sampled first analog signal with the second analog signal, and generate an indication signal, the indication signal indicating whether a comparison result between the sampled first analog signal and the second analog signal can be determined; wherein the control unit further comprises a compensating unit communicatively coupled to the comparing unit and configured to: wherein the control unit further comprises a successive approximation register (SAR) communicatively coupled to the comparing unit and configured to:
