Abstract

Una disposición de circuito provista con un primer amplificador, caracterizada porque la disposición comprende un segundo amplificador, teniendo los dos amplificadores una entrada común, siendo operados de modo equilibrado ("push-pull") y pudiendo ser conectada una impedancia de carga entre sus salidas, estando incluido un primer circuito de paso de corriente continua entra la salida del primer amplificador y un primer punto de polarización de corriente continua del segundo amplificador y estando incluido un segundo circuito de paso de corriente continua entra la salida del segundo amplificador y un segundo punto de polarización de corriente continua del primer amplificador, de tal modo que el acoplamiento de corriente continua que resulta de la salida del primer amplificador a la salida del segundo amplificador o de la salida del segundo amplificador a la salida del primer amplificador es de no-inversión, y cada uno de los circuitos de paso de corriente continua incluye un elemento de pasode corriente no-lineal.
