Syntheses of a PSPICE model of a titanium-dioxide memristor and Wien memristor generator

In this paper a PSPICE model of the equivalent circuit of the titanium-dioxide memristor is created based on its current-voltage relationship and using linear ionic drift model. By use of this computer model a Wien memristor generator is created. The oscillator circuit is analyzed and the basic relationships and time diagrams are given. The phase portrait of the system is also presented. The regulation of the output voltage magnitude and of the frequency is realized by changing the memristor's states using external pulse voltage sources. In the end, some concluding remarks about the memristor Wien generator investigated are given.
