A Triode-Based Analog Gate and Its Application in Chaotic Circuits

Signum and absolute value functions show great potential in chaos generation. Aiming to design an easy-to-use non-smooth circuit component, a Triode-based Analog Gate (TAG) is designed, which consists of only one triode, two op-amps and four resistors for analog signal selection. By choosing externa...

Summary:Signum and absolute value functions show great potential in chaos generation. Aiming to design an easy-to-use non-smooth circuit component, a Triode-based Analog Gate (TAG) is designed, which consists of only one triode, two op-amps and four resistors for analog signal selection. By choosing external resistors and signals, TAG can be easily extended to absolute value circuit, scalar multiplication circuit, analog selector-mixed subtraction circuit, sum signal selector circuit and piecewise selector circuit. The importance of this class of circuit modules is intensified by its low cost, high accuracy, easy integration and expansion. In this report, a hyperchaotic circuit, a circuit for attractor doubling and multi-scroll generation are consequently designed based on TAG circuits showing their great flexibility and extendibility.
