Abstract: Une boucle de verrouillage de phase horizontale utilisee dans un recepteur de television comprend une premiere et une seconde boucles et un oscillateur horizontal (34) qui genere un signal de rampe a une frequence egale a deux fois la frequence d'analyse de ligne. La premiere boucle verrouille le signal de l'oscillateur sur les impulsions de synchronisation horizontale. La sortie de l'oscillateur est decoupee en tranches (36) puis est divisee par deux (38) pour obtenir une forme d'onde de commande de cycle de travail a cinquante pour cent sur le detecteur de phase (30) dans la premiere boucle et sur un detecteur de phase (40) dans la seconde boucle. La seconde boucle comprend un decoupeur en tranches variables (44) qui fonctionne sur le signal de rampe de l'oscillateur de maniere a verrouiller le signal de retour du spot genere par l'etage de sortie horizontale (48) sur la forme de'onde de commutation du second detecteur de phase. Les deux boucles comprennent un circuit de division par deux (38, 46) qui assure l'obtention de formes d'ondes de commande de cycle de travail a cinquante pour cent.

Abstract: Un oscillateur horizontal pour un recepteur de television comprend un condensateur a mono-plaquette de nitrure (30). Le circuit comprend un amplificateur de courant de reference (64, 66, 68, 70, 72) qui genere un courant de reference de faible coefficient de temperature. En faisant varier le gain d'un circuit reflecteur de courant (78, 80, 82), le courant de reference est divise pour produire un petit courant de charge/decharge. Une chaine de polarisation resistive (36, 38, 40, 42) et un premier et un second condensateurs (30, 106) sont utilises pour fixer les tensions de crete superieure et inferieure du signal de rampe de sortie de l'oscillateur.

Abstract: A wideband linearized amplifier includes first and second differential amplifier sections each including differentially connected first and second pairs of transistors and a linearizing element coupled between the emitters of first ones of the second pair of transistors of each of the first and second differential amplifier sections which cancels the non-linear effects of the base-emitter junctions of the transistors of the amplifier. The bases of the first pair of transistors of the first and second differential amplifier sections are respectively coupled to differential inputs of the amplifier while the bases of the second pair of transistors of the first and second differential amplifier sections are coupled to a reference potential. The collectors of the first pair of transistors and the first transistor of the second pair of transistors of the first differential amplifier section and the collector of the second one of the second pair of transistors of the second differential amplifier section are coupled to a first output of the amplifier while the collectors of the first pair of transistors and the first one of the second pair of transistors of the second differential amplifier section and the collector of the second one of the second pair of transistors of the first differential amplifier section are coupled to a second output of the amplifier.

Abstract: 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-LINER 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 CIRCUT IS SUITABLE FOR USE IN VIDEO DETECTOR SYSTEMS.@@(FIG. 3)
