Abstract: According to an aspect of the disclosure, the disclosure provides an ADC which includes not limited to: a DAC configured to generate a positive input delta voltage and a negative input delta voltage, a comparator electrically connected to the DAC and configured to receive the positive input delta voltage to generate a first digital output value and to receive the negative input delta voltage to generate a second digital output value, a logic circuit configured to receive, from the comparator, the first digital output value and the second digital output value to generate a digital quantization code according to half of a sum of the first digital output value and the second digital output value, and a calibration circuit configured to receive the digital quantization code from the logic circuit and calibrate an output of the ADC according to the digital quantization code to eliminate an offset error value.
