Towards an Improved Anticipation Circuit with Self-Organized Resonance-Frequency-Adaption — Karlheinz Ochs and •Sebastian Jenderny — Ruhr University Bochum, Chair of Digital Communication Systems, Bochum, Germany

Inspired by the ability of an amoeba to anticipate environmental changes, an RLC circuit with a memristor in parallel has been proposed as an anticipation circuit. Here, the memristor enables a self-organized Q-factor adaption. Since this circuit's functionality is limited to an excitation with its resonance frequency, further research has been done to achieve an additional self-organized resonance-frequency adaption. Existing approaches are based on utilizing memcapacitors instead linear capacitors, where the memcapacitor models are very sophisticated. In contrast to this, in this work we develop a physically more meaningful memcapacitor to use it for an improved anticipation circuit. A wave digital emulation of the resulting circuit shows a self-organized resonance-frequency adaption, supporting the Q-factor adaption of the memristor.
