Title (EN) HIGH FREQUENCY DIGITAL-TO-ANALOG CONVERSION BY TIME-INTERLEAVING WITHOUT RETURN-TO-ZERO
(FR) CONVERSION NUMÉRIQUE-ANALOGIQUE HAUTE FRÉQUENCE PAR ENTRELACEMENT TEMPOREL SANS RETOUR À ZÉRO
Abstract:
(EN) An interleaved DAC configured to generate a set of second digital inputs responsive to a set of first digital inputs. Each second digital input is obtained by subtracting the other second digital inputs in the set from the corresponding first digital input. Two consecutive first digital inputs are shifted by a phase of T=1/ fs. The second digital inputs are supplied to a set of sub-DACs arrange in parallel. Each sub-DAC operates at a frequency of fs/R, and drives an analog output responsive to each second digital input for a duration of R×T. Clock signals used by two sub-DACs for converting two consecutive second digital inputs are offset by a phase of T. In each interval of T, summation of the analog signals output from the set of sub-DACs produces an analog value of a single first digital input, thereby achieving a data conversion speed of fs.
(FR) La présente invention concerne une CNA entrelacée conçue pour générer un ensemble de secondes entrées numériques en réponse à un ensemble de premières entrées numériques. Chaque seconde entrée numérique est obtenue par soustraction des autres secondes entrées numériques dans l'ensemble de la première entrée numérique correspondante. Deux premières entrées numériques consécutives sont décalées d'une phase T=1/ f s . Les secondes entrées numériques sont fournies à un ensemble de sous-CNA agencées en parallèle. Chaque sous-CNA fonctionne à une fréquence f s /R, et commande une sortie analogique en réponse à chaque seconde entrée numérique pendant une durée R×T. Des signaux d'horloge utilisés par deux sous-CNA pour convertir deux secondes entrées numériques consécutives sont décalés d'une phase T. Dans chaque intervalle T, la somme des signaux analogiques délivrés par l'ensemble de sous-CNA produit une valeur analogique d'une seule première entrée numérique, ce qui permet d'obtenir une vitesse de conversion de données f s .
