In order to make the chaotic oscillator of a higher degree of integration and wide frequency band,a new currentmode of chaotic oscillator was proposed. On the Venturi chaotic circuit basis,using CCII circuit instead of voltageoperational amplifiers,a sine wave oscillation circuit was first achieved,and then the two sinusoidal oscillation circuitswere coupled with the final realization of current mode by using NMOS chaotic oscillator. The experimental results showedthat compared it with the traditional chaotic oscillator,the Venturi chaotic oscillator is strong in power consumption,noisesuppression ability,the chaotic signal produced by it had been improved obviously in frequency band width and randomdegree,and more suitable for chip integration.
