Abstract: A dynamic high-resolution ADC according to an example embodiment may include a dynamic amplifier configured to amplify, by as much as a first gain, the sampled-and-held analog signal received from the sample and hold circuit; DAC configured to convert a digital signal input from a decoder into an analog signal; a residue signal amplifier connected to the dynamic amplifier and the DAC and configured to calculate a difference between an output signal of the dynamic amplifier and an output signal of the DAC and amplify the difference by as much as a second gain; an ADC connected to the residue signal amplifier and configured to convert an output signal of the residue signal amplifier into a digital signal; and a decoder connected to the ADC and configured to decode, into digital data, an output signal of the ADC input by the ADC.
