Abstract
(EN)
A radio frequency digital-to-analog converter (RFDAC) circuit includes an RFDAC array circuit including an array of cells arranged into a plurality of segments. Each segment of the plurality of segments is configured to process input data signals. The RFDAC array circuit is configured to process an input data based on activating a set of segments of the plurality of segments, forming a set of active segments, and when the sign of the input data is changed, deactivate a partially active segment of the set of active segments and activate a sign change segment within the RFDAC array circuit. The sign change segment includes a segment within the plurality of segments of the RFDAC array circuit that is different from the set of active segments.

Circuit de convertisseur numérique-analogique radiofréquence (RFDAC) comprenant un circuit de réseau de RFDAC comprenant un réseau de cellules agencées en une pluralité de segments. Chaque segment de la pluralité de segments est conçu pour traiter des signaux de données d'entrée. Le circuit de réseau de RFDAC est conçu pour traiter des données d'entrée sur la base de l'activation d'un ensemble de segments de la pluralité de segments, formant un ensemble de segments actifs, et lorsque le signe des données d'entrée change, désactiver un segment partiellement actif de l'ensemble de segments actifs et activer un segment de changement de signe dans le circuit de réseau de RFDAC. Le segment de changement de signe comprend un segment de la pluralité de segments du circuit de réseau de RFDAC qui est différent de l'ensemble de segments actifs.
