Abstract
CIRCUITO AMPLIFICADOR DE SEÑALES EN EL CUAL SE REDUCE LA DISTORSION NO LINEAL POR COMPENSACION DE LOS ARMONICOS PARES. CONSTA DE UN PRIMER CIRCUITO AMPLIFICADOR QUE INCLUYE DOS AMPLIFICADORES DIFERENCIALES CON ACOPLAMIENTO CRUZADO, COMPRENDIENDO CADA UNO DE DICHOS AMPLIFICADORES DOS TRANSISTORES A CUYA INTERCONEXION DE EMISOR COMUN ES APLICADA LA SEÑAL DE ENTRADAF DE UN SEGUNDO CIRCUITO AMPLIFICADOR IDENTICO AL PRIMERO; DE DOS CIRCUITOS INVERSORES, A TRAVES DE LOS CUALES LA INTERCONEXION DE EMISOR COMUN DE LOS DOS AMPLIFICADORES DIFERENCIALES DEL SEGUNDO CIRCUITO AMPLIFICADOR RECIBEN LA SEÑAL DE ENTRADA EN OPOSICION DE FASE CON RELACION A LA INTERCONEXION DE EMISOR COMUN DE LOS DOS AMPLIFICADORES DIFERENCIALES DEL PRIMER CIRCUITO AMPLIFICADOR.
