Abstract
A device for integrating an electric current during a period T, including an operational amplifier and a capacitor connected between a first input and an output of the amplifier, a second input of the amplifier being taken to a voltage VBUS, output voltage Vof the amplifier being saturated at a high voltage Vand a low voltage Vaccording to the charge quantity in the capacitor. The device also includes: a circuit for switching the terminals of the capacitor; and a circuit for triggering the circuit at least once during period Twhen voltage Vboth grows and is substantially equal to a reference voltage VREF, the voltage VREF being smaller than or equal to voltage V, and reference voltage VREF and voltage VBUS being selected to comply with relation 2·VBUS−VREF≥V; and a storage circuit for storing the number of triggerings having occurred between the initial time and the end time of the integration period.
