Abstract:
An analog-digital conversion circuit (ADC1) includes: a capacitor (C1); a charge and discharge control section (6) that puts, into the capacitor (C1), an electric charge corresponding to an input current of a first period and that causes an electric charge corresponding to an input current of a second period to be discharged from the capacitor (C1); and a digital conversion section (5) that converts an amount of electric charge of the capacitor (C1) into a digital signal.
