Description

technical field [0001] The invention relates to a chaotic signal generator based on a generalized memristor Colpitts oscillator. The generalized memristor is introduced into a fourth-order Colpitts oscillator to form a novel chaotic signal generator. Background technique [0002] A Colpitts oscillator is an electronic oscillator named after its inventor, Edwin H. Colpitts. The Colpitts oscillator can be seen as the dual of the Hartley oscillator. Colpitts oscillators use two capacitors and an inductor, while Hartley oscillators use two inductors and a capacitor. [0003] The Colpitts oscillator circuit, as a typical capacitor three-point feedback oscillator circuit, is a well-known oscillator circuit. Colpitts oscillator circuits are widely used in signal sources from very low frequency bands to millimeter wave frequency bands. In the application of the traditional Colpitts oscillator circuit, people pay attention to its simple harmonic oscillation characteristics, and tr...
