PWL Window Function for Nonlinear Memristive Systems

Memristor and memristive circuits exhibit a hysteresis v-i characteristic, which is strongly dependent on the state variable function. In this way, controlling the state variable performance can give a more realistic description of the device. This work presents the use of a PWL window function to establish the behavior of the state variable function with the purpose of analyzing the influence of the novel window function in the characteristic curves of the memristive systems, such as: the pinched hysteresis loop and the memristance. The notion of asymmetrical window functions is introduced in order to catch sight of the advantages of the PWL window functions compared to the typical window functions. Moreover, a simple comparison regarding several window functions is achieved.
