Abstract

AMPLIFICADOR OPERACIONAL EN CIRCUITO INTEGRADO DE ALTA TENSION.COMPRENDE UN CIRCUITO DE ENTRADA (10) Y UN CIRCUITO DE SALIDA (12). EL CIRCUITO DE ENTRADA (10) CONSTA DE DOS TRANSISTORES DE ALTA TENSION (Q1, Q2) DOS TRANSISTORES DE CARACTERISTICA DE BAJA TENSION (Q3, Q4) ACOPLADOS A LOS PRIMEROS, Y DOS TRANSISTORES MAS (Q7, Q8), ACOPLADOS A LOS SEGUNDOS. EL CIRCUITO DE SALIDA TIENE DOS TRANSISTORES DE ALTA TENSION ACOPLADOS AL TERCER PAR DE TRANSISTORES.ADMITE CONFIGURACIONES CON CIRCUITOS ADICIONALES.
