Abstract
A new implementation of hyperchaotic modified canonical Chua circuit using junction field-effect transistors (JFETs) is proposed. The design is based on a source coupled JFET circuit to approximate a smooth cubic non-linearity and a two-terminal negative resistance element containing a p-n-p silicon transistor and an n-channel JFET. The realization is supported by Orcad Pspice simulation and numerical MATLAB results. The hyper-chaotic nature is confirmed by two positive Lyapunov exponents associated with the attractor which is a fractal with a Lyapunov dimension between 3 and 4.
