ABSTRACT:
The present invention concerns a process for correcting the output level of a charge-transfer device, as well as a device for operating the same. Said process comprises different steps, respectively a first step where the quantities of charges corresponding to a reference signal that are stored in N stages are read successively and the values being function of the different quantities of charges read, are stored in a memory; and a second step, where before each read-out of a charges quantity, the precharge level of the output stage is modulated in function of the value of the same rank stored in the memory.
