交叉耦合混沌信号源电路建模与设计
Circuit model and design of cross-coupled chaotic signal generator
摘要
Abstract
A cross-coupled chaotic signal generator circuit is presented.Chaotic oscillation conditions of the cross-coupled circuit are proved through establishing nonlinear chaotic model.The stability enhancing mechanism of left-and-right complementary property is analyzed by splitting the cross-coupled circuit into two complementary two-stage chaotic circuits.The chaotic attractor and output spectrum are simulated and tested by tuning the port impedance.Results show that,the stable chaotic output impedance of the cross-coupled chaotic circuit is below 80 Ω,the stability is enhanced by 6 times than that of the conventional circuit with 500 Ω output impedance.The output chaotic signal spectrum is divided into three bands covering 1.5～11.4 GHz,which is enhanced by 50%than that of the conventional circuit.关键词
