Abstract

Un dispositivo amplificador que comprende un primero y un segundo elementos amplificadores, cuyas salidas están conectadas a una carga, y un circuito de diferencia que comprende un atenuador, en el que la señal de salida en el primer elemento amplificador es comparada con la señal de entrada, después de lo cual una señal de correción resultante es aplicada al segundo elemento amplificador, caracterizado porque los dos elementos amplificadores, que según el cado pueden estar precedidos por preamplificadotes, adoptan la forma de amplificadores de potencia, y el segundo elemento amplificador está también provisto de un circuito de diferencia sustancialmente idéntico que comprende un atenuador, que suministra la señal de correción al primer elemento amplificador, aplicándose una señal a amplificar a ambos elementos amplificadores.
