Abstract
A charge/voltage conversion device of a CCD type charge transfer read register comprises a read diode and a read amplifier, wherein the read amplifier comprises a first amplification stage enabling the conversion, into current variations (.DELTA.I), of the voltage variations (.DELTA.Vg) collected at the terminals of the read diode and a second amplification stage enabling a reading to be made of said current variations. The disclosed device can be applied especially to photosensitive devices enabling the conversion of a light image into an electrical signal.
