Abstract
Un receptor de banda base digital (DBB) para recibir y procesar una senal de comunicacion inalambrica. Receptor DBB incluye al menos un amplificador de bajo ruido (LNA), al menos un demodulador, un circuito de descarga de corriente continua (DC) y un circuito de control de LNA. El LNA amplifica selectivamente la senal de comunicacion. El demodulador da salida a componentes analogos de senal real e imaginaria sobre pesos de senal real e imaginaria, respectivamente, en respuesta a la recepcion de la senal de comunicacion desde el LNA. El circuito de descarga DC descarga selectivamente DC en acumulacion sobre al menos uno de los pesos de senal real e imaginaria. El circuito de control de LNA activa y desactiva el LNA.
