Abstract

一种模数信号转换系统(300)及方法，所述系统(300)包括一数字信号拆分单元(401)，一第一数字信号存储单元(411)，一第二数字信号存储单元(421)，一第一存储电容选择单元(412)及一第二存储电容选择单元(422)，所述数字信号拆分单元(401)用于将所述模数信号转换系统(300)输出反馈的以比特数z表示的数字控制信号的信号码N拆分为以比特数x表示的第一信号码K及以比特数y表示的第二信号码P，所述第一及第二数字信号存储单元(411,421)分别用于依序储存所述第一信号码K及所述第二信号码P，所述第一及第二存储电容选择单元(412,422)分别用于选择所述第一信号码K及所述第二信号码P的存储电容，从而大幅减少了系统内部的引线与硬件数量，因而节省了耗电量及提升了系统整体的运作效能。
