Title
(EN) LINEAR FULL WAVE RECTIFIER CIRCUIT
(FR) CIRCUIT REDRESSEUR LINEAIRE BIPHASE
Abstract
(EN) A rectifier circuit (80) which produces a nearly perfect full wave rectified output signal in response to receiving a differentially applied input signal. The rectifier circuit comprises a pair of rectifiers (88, 86, 90, 92 and 102, 104, 106, respectively) that have substantially identical non-linear transfer characteristics with the first one of the rectifiers receiving the differentially applied input signal at first and second (82, 84) inputs. A current mirror (96) having an input coupled at a first node (94) to an output of the first rectifier provides an output signal at an output thereof which is substantially identical to the output signal appearing at the output of the first rectifier. The second rectifier has an output connected at a second node (98) to the output of the current mirror. A feedback circuit (100, 108) is coupled between the second node and an input of the second rectifier to cause the output signal appearing at the output of the second rectifier to be a full wave rectified version of the differentially applied input signal. The rectifier circuit is suitable for use in video detector systems.
(FR) Un circuit redresseur (80) produit un signal de sortie redresse biphase presque parfait en reponse a la reception d'un signal d'entree applique differentiellement. Le circuit redresseur comprend une paire de redresseurs (88, 86, 90, 92 et 102, 104, 106, respectivement) qui ont des caracteristiques de transfert non lineaires sensiblement identiques a celle du premier des redresseurs recevant le signal d'entree applique differentiellement a la premiere et a la seconde entrees (82, 84). Un reflecteur de courant (96) ayant une entree couplee a un premier noeud (94) sur une sortie du premier redresseur envoie un signal de sortie qui est sensiblement identique au signal de sortie apparaissant a la sortie du premier redresseur. Le second redresseur possede une sortie connectee en un second noeud (98) sur la sortie du reflecteur de courant. Un circuit de reaction (100, 108) est couple entre le second noeud et une entree du second redresseur pour faire en sorte que le signal de sortie apparaissant a la sortie du second redresseur soit une version redressee biphasee du signal d'entree applique differentiellement. Le circuit redresseur se prete a une utilisation dans des systemes detecteurs video.
