Title (EN) PIPELINED ADC HAVING THREE-LEVEL DAC ELEMENTS
(FR) CAN EN PIPELINE AYANT DES ÉLÉMENTS DE CNA À TROIS NIVEAUX
Abstract: front page image
(EN)A pipelined analog-to-digital converter (ADC) includes three-state digital-to-analog converter (DAC) switches or segments. An example DAC 300 has logic circuitry 304 and three-state DAC switches 302-1 to 302-k. In operation, the logic circuitry 304 receives a control word from the ADC and generates a plurality of control signals for each three-state switch. The switches may include transistors and a current source so that, based on the control signals, the switches can generate "+1", "-1"or "0" logic states.
(FR)Un convertisseur analogique/numérique (CAN) en pipeline comprend des commutateurs ou segments de convertisseur numérique/analogique (CNA) à trois états. Un CNA 300 exemplaire possède un circuit logique 304 et des commutateurs CNA à trois états 302-1 à 302-k. En fonctionnement, le circuit logique 304 reçoit un mot de commande du CAN et génère une pluralité de signaux de commande pour chaque commutateur à trois états. Les commutateurs peuvent comprendre des transistors et une source de courant permettant aux commutateurs, à partir des signaux de commande, de générer les états logiques "+1", "-1" ou "0".
