DISPOSITIF CONVERTISSEUR NUMERIQUE-ANALOGIQUE

摘要

A digital-to-analogue converter arrangement employs a digital-to-analog converter circuit (10) of a type producing an output voltage V(n') such that: where k is a constant, E is a voltage applied to a reference voltage input, n' is a binary number applied to a binary signal input and M' is the maximum value n' can attain. The converter arrangement includes a negative feedback network (20) coupled between the output (13) of the digital-to-analogue converter circuit and the reference voltage input (14).
