Patent attributes
An analog-to-digital converter according to one or more embodiments is disclosed that converts an analog input to a digital converted value by repeating a conversion data generation operation by a conversion data generator, a potential generation operation by a capacitance DAC, and a comparison operation by a comparator for a resolution bit, the analog-to-digital converter. a comparator operation signal generation circuit predicts the time when a potential generated by the capacitance DAC becomes settled based on a charging or discharging time to a capacitance element whose characteristics are equal to those of the capacitance used in the capacitance DAC, and generates a comparator operation signal to allow the comparator to start the comparison operation.
