Generalized model for Memristor-based Wien family oscillators

Abstract

In this paper, we report the unconventional characteristics of memristor in Wien oscillators. Generalized mathematical models are developed to analyze four members of the Wien family using memristors. Sustained oscillation is reported for all types though oscillating resistance and time dependent poles. We have also proposed an analytical model to estimate the desired amplitude of oscillation before the oscillation starts. These memristor-based oscillation results are in good agreement with simulation results.

Sandwich synchronization of memristor-based hyperchaos systems with time delays

“…A lot of memristor oscillator systems have been used in generating signals which are found in satellite communications, radio, switching power supply, etc. [4][5][6][7][8][9][10]. With the potential memristor applications, it is necessary to do some deep research on the related nonlinear memristor-based oscillator systems [11][12][13].…”

Memristor-based memory: The sneak paths problem and solutions

“…Since the first reported use of the memristor, it received a significant of attention in the research community. In addition to be used as a memory element [2,[17][18][19][20][21][22][23][24][25][26], the memristor has found many applications in oscillators [27][28][29][30], logic and arithmetic circuits [31,32], programmable analog circuits [33,34], and in modeling and emulation of natural phenomena [35,36].…”

Chaos Control in Memristor-Based Oscillators Using Intelligent Terminal Sliding Mode Controller

“…They are electrical circuits that produce sine or square wave in their output. Among different kinds of oscillators there are memristor-based oscillators which are achieved by replacing one or more elements of conventional oscillator circuits with a memristive system, such as memristor-based Wien-oscillator [9], memristor-based relaxation oscillator [10], Op-Amps memristor Based oscillator [11] and Chua's memristor-based oscillator [12]. Memristor was proposed by Leon Chua in 1971 [13] and mentioned as the fourth element of electrical circuits.…”
