Otherwise , an active integral chaotic measuring circuit is suggested based on the analysis of the present nonlinear circuits in this paper , which gets rid of nonlinear distortion of map function in constant - voltage mode and defect of constant - current source operating on - off state . using a general operational amplifier , high precision can also be obtained . a nth - order chaotic measuring system can be composed of its interconnection 另外,本文在分析原有非线性电路的基础上提出一种有源积分式混沌测量电路,它克服了恒压式测量电路映射函数存在非线性失真、恒流式测量电路不宜工作在开关状态的不足,利用普通的运放也获得较好的测量精度。
