实现高精度浮地测量的一种新方法

A New Method of Realizing High Precision Floating Measurements

浮地测量是抑制地电位差或共模电压的一种高精度测量。本文研究了如何利用运算放大器和RC元件实现浮地测量,提出了一种新型的高精度浮地测量方法。这种方法有助于提高整机线路的集成度,便于进行计算机辅助分析与设计.在IBM PC/XT上进行实验,结果满意。

Floating measurements are one of high precision measurements with suppressing differences between grounds or common mode Voltages. It is studied how to realize floating measurements by utilizing op-amps and RC elements in this paper. A new method of high precision floating measurements is presented, It helps to increase the amount of integrated rircuit in a complete set of apparatus and is convenient to carry on CAA and CAD.Experimen tat results are satisfied in the IBM PC/XT.
