Schmitt Non-Gate Chaotic Circuits: Phase Diagram, Complex Walking, and Spring Testing

Small is beautiful. The highlights are to focus on the effective new applications of Schmitt non-gate, forming two novel chaotic circuits with simple structures and clear principles. RC Wien-bridge oscillator chaotic circuit uses series Schmitt non-gate and diode as nonlinear feedback block. Schmitt non-gate multi-vibrator chaotic circuit relies on RCR unit for differential action and current protection at the gate output end. The complexity measures of new 3D chaotic signals are modeling in phase diagram, complex walk and spring test. The mini demonstration of bifurcation diagrams of two simplest 555 timer Schmitt chaotic circuits be reported firstly.
