Abstract

L'invention a pour objet un étage différentiel utilisant le transfert de charges dans un semi-conducteur. Il comporte principalement : deux canaux 1 et 2 de transfert de charges qui reçoivent respectivement les deux signaux S1 et S2 dont il leur faut réaliser la différence; un système d'électrodes assurant sur application de potentiels périodiques la propagation de chacun des signaux avec un déphasage relatif de pi ; une électrode commune 3 aux deux canaux, qui fournit un signal proportionnel à la différence entre les signaux initiaux. Ce dispositif est notamment applicable à la réalisation d'étages de sortie pour filtres à transfert de chargeaThe subject of the invention is a differential stage using the transfer of charges in a semiconductor. It mainly comprises: two charge transfer channels 1 and 2 which respectively receive the two signals S1 and S2 from which they must make the difference; a system of electrodes ensuring, on the application of periodic potentials, the propagation of each of the signals with a relative phase shift of pi; a common electrode 3 to both channels, which supplies a signal proportional to the difference between the initial signals. This device is particularly applicable to the production of output stages for charge transfer filters.
