A main ADC architecture for low power system is charge redistribution successive approximation register.In this thesis,8bits sar adc is designed. The main research is sample and hold circuit, D/A convert ,digital control logic etc.

目前在低功率系统中主流的类比数位转换器架构为电荷重新分布式的循渐近式逼近法，本设计8bits逐步逼近式类比数位转换器，主要研究了A/D转换器中包含取样保持电路、D/A转换器、数位逻辑控制等设计。

The ADC is pipelined, including a single-input/difference-output sample/hold circuit and nine stage subcircuits. The preceding eight stages are 1.5bits/stage, and the last stage consists of two comparators. Every input sample is converted into 18 bits binary signals, and these binary signals are converted into 10 bits binary signals through digital correction circuit.

模数转换电路采用流水线式的结构，包括具有单端输入/差动输出功能的采样保持电路和九级的子电路，前八级子电路使用1.5位/级的结构，最后一级使用两个比较器实现，每个输入值被转换为18位的二进制代码，通过数字纠正技术最终实现10位的输出，按照前端电路的应用要求，这个模数转换器实现1.33MHz的采样速率。
