Abstract
Un amplificador Clase A de terminal único incluye un componente de amplificación (por ejemplo, un tubo de vacío) que tiene al menos un terminal de salida, un terminal de referencia y un terminal de control. El terminal de control recibe una señal de entrada que varía en el tiempo. El componente de amplificación responde a la señal de entrada variable de tiempo para variar un voltaje de salida en el terminal de salida y para variar una corriente que fluye entre el terminal de salida y el terminal de referencia. Una carga está acoplada a CA al terminal de salida. Una fuente de corriente regulable tiene una entrada de voltaje acoplada al terminal de salida y tiene una salida de corriente regulable acoplada al terminal de salida. La fuente de corriente regulable está configurada para aumentar la corriente regulable para proporcionar corriente a la carga cuando el voltaje de salida en el terminal de salida del componente de amplificación aumenta y para disminuir la corriente regulable cuando el voltaje de salida en el terminal de salida del componente de amplificación disminuye.
