Abstract

Una etapa de amplificación de tres terminales que incluye un transformador con un arrollamiento conectado al circuito de carga de la etapa y un segundo arrollamiento conectado al circuito de entrada de la etapa, siendo las polaridades respectivas de los arrollamientos y su relación de vueltas tal que una parte de la tensión de salida (o corriente) se retrae de la tensión de entrada ( o corriente).
