Abstract
Provided is an AD conversion apparatus including: a reference signal generating circuit configured to output a first reference signal and a second reference signal, whose voltages change with time; a comparison circuit configured to perform a comparison between a voltage of the analog signal and the voltage of the first reference signal; a control circuit configured to generate and output digital data based on the comparison; a digital-to-analog converter configured to generate, using the second reference signal, a signal whose voltage changes with time from a comparison base voltage, the comparison base voltage being based on the digital data, and configured to output the signal to the comparison circuit; and a counter configured to generate a count value by measuring an elapsed time. The comparison circuit is further configured to perform a comparison between the voltage of the analog signal and the signal output from the digital-to-analog converter.
