Abstract

Se proporciona un arreglo de circuito para la desmodulacion de un voltaje modulado (ASK) a traves de un cambio de la amplitud entre un nivel inferior y un nivel superior. Entonces se genera en un primero y un segundo circuitos de carga un voltaje (V1, V2) de carga, en donde un dispositivo (S1) de desacoplamiento, desacopla el primer circuito (C1, i1) en una proporcion predeterminada entre el voltaje (V2) de carga del segundo circuito (C2, i2) de carga y un voltaje de entrada (UHF) del circuito rectificador (D1, D2).
