GENERATEUR DE RAMPE, CONVERTISSEUR ANALOGIQUE-NUMERIQUE ET NUMEREIQUE -ANALOGIQUE ET CODEUR ET DECODEUR TELEPHONIQUE UTILISANT UN TEL GENERATEUR

摘要

The invention relates to ramp generators by which it is possible to obtain an electrical voltage which represents a ramp of a required form in dependence upon a given parameter. The invention comprises using a charge transfer device in which the charge transferred is measured in dependence upon a parameter associated with the weighting of the electrodes of the device. This weighting is fixed according to the required form of the ramp.
