Abstract
An analog-to-digital converter includes: a sample/hold circuit, which samples an analog signal, and outputs a first voltage; a digital-to-analog conversion circuit, which converts a digital signal to output a second voltage; an amplifier, which amplifies the first voltage and the second voltage; a noise shaping filter, which integrates a residual voltage corresponding to a difference between the amplified first voltage and the amplified second voltage, and generates a first integration voltage and a second integration voltage; a comparator, which compares a sum of the amplified first voltage, the first integration voltage, and the second integration voltage with the amplified second voltage; and a SAR logic, which outputs the digital signal according to a comparison result of the comparator, and controls the digital-to-analog conversion circuit.
