Abstract

Memristor is a passive circuit element which firstly presented to
science world by Leon Chua in 1971. Chua showed a missing link among four
fundamental circuit variables which generate basic passive circuit elements.
Chua described this missing link between charge and flux, named it as
memristor. Memristor is firstly realized by Stanley Williams and his team from
HP (Hewlett Packard) research laboratories in 2006. In this study, doped and
undoped TiO₂ are sandwiched between two Pt layers in nano scale. And
this element demonstrated voltage-current characteristic like memristor.
Physically implementation of memristor is announced with a paper to science
world in 2008. The studies about memristor have quite increased along with this
study. In this paper, a new PWL (Piece Wise Linear) memristor model is obtained
thereby linearizing current-voltage characteristic of memristor. The equivalent
circuit is derived from this model, built in Simulink and results are observed.
The results are compared with other studies in literature and obtained results
have been shared.
