Title (EN) PULSE WIDTH MODULATED CIRCUITRY FOR INTEGRATED DEVICES
(FR) CIRCUIT MODULÉ EN LARGEUR D'IMPULSION POUR DISPOSITIFS INTÉGRÉS
Abstract:
(EN) An apparatus for producing a separate pulse width modulation signal for each of a plurality of integrated devices, comprising circuitry for each integrated device having structures that receive and convert a digital signal for each integrated device to an analog voltage level; sample the analog voltage level and storing such analog voltage level; and compare the stored analog voltage level to a common dynamic reference signal and producing a variable width pulse having a first level when the reference signal is above the analog voltage level and a second level when the reference signal is below the analog voltage level, wherein the common dynamic reference signal is the same signal for each integrated device
(FR) L'invention concerne un appareil permettant de produire un signal de modulation de largeur d'impulsion pour chacun d'une pluralité de dispositifs intégrés, lequel comprend un circuit pour chaque dispositif intégré comportant des structures qui reçoivent et convertissent un signal numérique pour chaque dispositif intégré en un niveau de tension analogique, échantillonnent le niveau de tension analogique et stockent ce niveau de tension analogique, et comparent le niveau de tension analogique stocké à un signal de référence dynamique commun et produisent une impulsion de largeur variable ayant un premier niveau lorsque le signal de référence est au-dessus du niveau de tension analogique, et un second niveau lorsque le signal de référence est en dessous du niveau de tension analogique, le signal de référence dynamique commun étant le même pour chaque dispositif intégré.
