Abstract:
An analog-to-digital conversion device includes a plurality of counting period supply units that supply a period of length according to a voltage of an analog signal inputted into each counting period supply unit based on the voltage of the analog signal as a counting period, a plurality of counter circuits which are connected to a common power supply and which perform a counting operation that counts a count value in the counting period different from each other and generate a digital signal indicating the count value, and a plurality of compensation circuits which are connected to the power supply and which operate so that the greater the number of counter circuits that stop the counting operation among the plurality of counter circuits, the greater the number of the compensation circuits that operate.
