Abstract: A dual-slope analog-to-digital converter includes a switching circuit, an integrating circuit, a dual comparison circuit, and a control circuit. The integrating circuit is configured to perform a charging operation having a first slope, based on a magnitude of an input voltage selected by the switching circuit, and a discharging operation having a second slope, based on a magnitude of the reference voltage selected by the switching circuit, and output a first voltage. The dual comparison circuit is configured to output a first comparison signal by comparing the first voltage with a first reference voltage and output a second comparison signal by comparing a second reference voltage, higher than the first reference voltage, with the first voltage. The control circuit is configured to output a digital value corresponding to the magnitude of the input voltage, based on a first count value and a second count value.
