具有漂移和偏置校正的A/D转换器的设计

The Experimental Analysis for stiffness of the HTSD linear Motion Guide

本文描述了一种微处理器控制的模数（Ａ／Ｄ）转换器，它相对于温度的变化有较高的精度和稳定性，而不要求高精度的元件和低漂移放大嚣。介绍了模拟电路的工作及其微处理器控制这一工作的顺序和误差的校正计算，讨论了该转换器的精度和残存的误差，并以实验测试证实了所提出的结论。

This paper takes the HSTD linear motion guide as a experimental objective,compares the caculating results in theory with the experimental data of stiffness under the vertical load,provides the basis users and the evalution of the products.
