摘要
An analog/digital converter device associated with a detector of an image sensor, including: a comparator capable of receiving the analog signal and delivering a two-states output signal, able to adopt, depending on the analog signal, a first stable state or a second state, a charge injector capable of changing the analog signal by injection of at least one quantity of charges into the capacitor, and a mechanism for commanding the charge injector, capable of receiving the two-state signals and capable of triggering, depending on the two-state signals, plural injections of charges between at least two successive changes in state of the signal, from the first state to the second state and from the second state to the first state.
