Abstract
PARA LA CREACION DE UN CIRCUITO CON AMPLIFICACION AJUSTADA O AJUSTABLE NO INVERSORA, SE HA PREVISTO UNA DISPOSICION DE CIRCUITO CON UNA ENTRADA (E), UNA SALIDA (A), UN AMPLIFICADOR OPERACIONAL (3) Y UN COPIADOR DE CORRIENTE (8, 8 ) QUE A SU VEZ TIENE UNA SECCION DE ENTRADA CON UNA ENTRADA DE CORRIENTE Y UNA SECCION DE SALIDA CON UNA SALIDA DE CORRIENTE. LA SALIDA (33) DEL AMPLIFICADOR OPERACIONAL (3) ES TAMBIEN LA SALIDA DE SEÑAL (A) DE LA DISPOSICION DE CIRCUITO, CUYA ENTRADA NO INVERSORA (31) ESTA A UN POTENCIAL DE REFERENCIA (P SUB,1}). LA SALIDA (33) ESTA UNIDA A TRAVES DE UNA RESISTENCIA (1) A LA ENTRADA INVERSORA (32), Y LA ENTRADA (E) DE LA DISPOSICION DE CIRCUITO, POR UNA RESISTENCIA (2), A LA ENTRADA DE CORRIENTE DEL COPIADOR DE CORRIENTE (8), CUYA SALIDA DE CORRIENTE ESTA A LA ENTRADA INVERSORA (32) DEL AMPLIFICADOR OPERACIONAL (3). LA SECCION DE SALIDA DEL COPIADOR DE CORRIENTE ESTA CONECTADA A UN POTENCIAL DE REFERENCIA (P SUB,2}), Y SU SECCION DE ENTRADA AL POTENCIAL DE REFERENCIA (P SUB,1}).
