Chaotic Measured Circuit of Constant Current and Simulation Analysis

In this paper,the constant current circuit is analyzed and designed basd on the parameter sensibility and the initial value sensibility of this chaotic system.According to signal dynamics theory,the measured value can be obtained by computing the space distance of two trakcs and building signal sequence space.The degree of belief and availability is tested by simulating. The measured circuit has a lot of merits,such as,simpleness,high sensitivity and distinguishability,less nonlinear errors,and so on.This metod supplies a new way for the use of chaotic theory in measurement.
