Memristors

14:13

Morning work is done, starting work on my thesis.

14:20

Reading a paper on dynamical behaviour of iontonic memristor-capacitor networks. Need to decide on a model to use for my research. basically, we have an infinite-dimensional dynamical system based on a time-delay parameter, and a 2-dimensional system based on HP memristors.

14:32

The trade-off that we are making is one of low dimensionality within our dynamical system and few components used in the final system.

14:50

I should look into how the HP memristor and our own differ. Maybe one can be transformed into the other using other circuit items?

15:03

Pivoting research towards general (chaotic) dynamical systems now. Found some leads that I wish to work out on pen-and-paper.

15:40

Some chaotic systems I have found in my research:

• Fast / Slow systems (3 dimensional, 1 extra component)
• Chua circuit with nonlinear resistor subbed for memristor (4 dimensional, 3 extra components)
• HP memristor circuit (2 dimensional, component replacement)
• Time-delay memristor circuits (infinite dimensional, no extra components)

15:57

Topological chaos in the parallel inductor-capacitor-memristor circuit. Interesting paper I just found.

16:14

Adding to the chaotic systems

• Parallel LCM circuit. (3 dimensional, 1 extra component)
• Resistance switching models (3 dimensional, not sure how to augment)
• Edge of chaos kernels (EOCK, 3 dimensional, 1 extra component?)

16:19

Found a research paper using the MMS memristor model. May need to investigate further.

17:07

Found and read a bunch of research paper, saved the important ones. Now I’ll probably be looking into all of these and making a selection of ones to present to my supervisors.
