Abstract

Se describe un amplificador de conmutación digital mejorado. El amplificador utiliza un filtro de paso en la entrada del comparador de conmutación para dar una relación de señal a ruido mejorada, en la salida final. En otro aspecto de la invención, se usa un retardo de propagación para producir la oscilación estacionaria del circuito amplificador.
