Abstract
Convertisseur présentant un pouvoir de résolution élevé Il comprend : une source de tension de commande, un condensateur d'échantillonnage Cj , un condensateur d'accumulation nC, un circuit de mesure T1 , T2 transférant des paquets de charges entre le condensateur d'échantillonnage et le condensateur d'accumulation, un circuit d'entrée de tension de signal analogique, et un circuit de sortie comptant le nombre de paquets de charges qu'il faut transférer pour charger le condensateur d'accumulation jusqu'à une valeur déterminée par le signal analogique d'entrée. Application aux convertisseurs analogiques-numériques.Converter with high resolving power It includes: a control voltage source, a sampling capacitor Cj, an accumulation capacitor nC, a measuring circuit T1, T2 transferring charge packets between the sampling capacitor and the accumulation capacitor, an analog signal voltage input circuit, and an output circuit counting the number of charge packets that must be transferred to charge the accumulation capacitor to a value determined by the signal analog input. Application to analog-to-digital converters.
