Title (EN) DIGITAL-TO-ANALOG CONVERTER WITH CONVERSION CELLS CONVERTING TERNARY SIGNAL PAIRS
(FR) CONVERTISSEUR NUMÉRIQUE/ANALOGIQUE AVEC DES CELLULES DE CONVERSION CONVERTISSANT DES PAIRES DE SIGNAUX TERNAIRES
Abstract:
(EN) The disclosure relates to a digital-to-analog converter, DAC (100) for converting a digital input signal (x[n], 110) to an analog output signal (y), the DAC (100) comprising: an encoder (102), configured to generate a pair of ternary signals (c1[n], c2[n], 103, 104) based on the digital input signal (110); and a pair of single bit DACs (105, 106) coupled to the encoder (102) and configured to convert the pair of ternary signals (103, 104) to a pair of analog output states (y1[n], y2[n], 107, 108), wherein each ternary signal (103, 104) of the pair of ternary signals (103, 104) comprises a high, a zero and a low state producing a corresponding output state (107, 108) at the single bit DAC (105, 106) coupled with the respective ternary signal (103, 104).
(FR) Cette invention concerne un convertisseur numérique-analogique, CNA (100), conçu pour convertir un signal d'entrée numérique (x[n], 110) en un signal de sortie analogique (y), le CNA (100) comprenant : un codeur (102), configuré pour générer une paire de signaux ternaires (c1[n], c2[n], 103, 104) sur la base du signal d'entrée numérique (110) ; et une paire de CNA à un seul bit (105, 106) couplés au codeur (102) et configurés pour convertir la paire de signaux ternaires (103, 104) en une paire d'états de sortie analogiques (y1[n], y2[n], 107, 108), chaque signal ternaire (103, 104) de la paire de signaux ternaires (103, 104) comprenant un état haut, un état zéro et un état bas produisant un état de sortie correspondant (107, 108) au niveau du CNA à un seul bit (105, 106) couplé au signal ternaire respectif (103, 104).
