Abstract

UN APARATO PARA CONVERTIR UNA SEÑAL ANALOGICA, EQUILIBRADA (VINB, VINC), EN UNA SEÑAL DIGITAL MEDIANTE REDISTRIBUCION DE CARGA DE UNA PLURALIDAD DE CONDENSADORES (1©5, 1K©4K). ESTOS ESTAN REUNIDOS EN DOS GRUPOS Y PUEDEN CONECTARSE SELECTIVAMENTE, AL MENOS DURANTE UNA FASE DE APROXIMACION, A DOS TENSIONES DE REFERENCIA DIFERENTES (VR,MASA) CON AYUDA DE CONMUTADORES (6©10, 6K©10K). CADA UNO DE LOS GRUPOS DE CONDENSADORES ESTA DISPUESTO PARA ACTUAR CON ARREGLO AL POTENCIAL EN SUS PUNTOS RESPECTIVOS (13, 13K) DURANTE UNA FASE DE APROXIMACION, Y UN COMPARADOR ESTA DESTINADO A COMPARAR LOS POTENCIALES EN ESTOS PUNTOS. LOS CONMUTADORES ESTAN CONTROLADOS POR MEDIOS (18) DE CIRCUITO LOGICO PARA MUESTREO Y APROXIMACION, QUE GENERAN PALABRAS DIGITALES DE CONTROL EN RESPUESTA AL RESULTADO COMPARATIVO DEL COMPARADOR.
