Information

This is an implementation of the Shinriki oscillator as described in [Lueck1995] and [Shinriki1981] .

Note that the operational amplifier of the NIC (negative impedance converter) needs to be modeled with high no-load amplification (but not infinite) and saturation of the output voltage between positive and negative supply.

Plot v1 vs. v2.
Default parameter R2 = 20000 Ω shows periodic results.
Change parameter R2 = 8400 Ω to obtain chaotic results.
