Abstract

Se provee un sistema de convertidor de analógico a digital (ADC) intercalado en el tiempo que comprende un puerto de entrada configurado para recibir una señal analógica, una matriz de ADC que comprende M, M=2, ADCs dispuestos en paralelo. Cada ADC está configurado para recibir y convertir una porción de la señal analógica a una señal digital a una tasa de muestreo fs. El sistema ADC comprende además un ADC de referencia configurado para recibir y para convertir la señal analógica en una señal digital de referencia a una tasa de muestreo promedio fref inferior a fs. Cada instante de muestreo del ADC de referencia corresponde a un instante de muestreo de un ADC en la matriz de ADCs, y el ADC para seleccionar para cada instante de muestreo de ADC de referencia es aleatorizado en el tiempo. El sistema ADC también comprende un módulo de corrección configurado para ajustar las salidas de señal digital de la matriz de ADC a una señal de salida digital corregida con base en muestras de la señal digital de referencia y las señales digitales de los correspondientes ADCs seleccionados. También se provee un método para la conversión de analógico a digital intercalado en el tiempo.
