Circuit simulation and physical implementation for a memristor-based colpitts oscillator

Abstract

This paper implements two kinds of memristor-based colpitts oscillators, namely, the circuit where the memristor is added into the feedback network of the oscillator in parallel and series, respectively. First, a MULTISIM simulation circuit for the memristive colpitts oscillator is built, where an emulator constructed by some off-the-shelf components is utilized to replace the memristor. Then the physical system is implemented in terms of the MULTISIM simulation circuit. Circuit simulation and experimental study show that this memristive colpitts oscillator can exhibit periodic, quasi-periodic, and chaotic behaviors with certain parameter’s variances. Besides, in a sense, the circuit is robust with circuit parameters and device types.

“…These are the remarkable properties [2] of chaotic systems. Sometimes, the chaotic systems are deterministic [3,4] and they have long-term unpredictable behavior [5,6].…”

Dimensionality Reduction Reconstitution for Extreme Multistability in Memristor‐Based Colpitts System

“…In the past few years, various memristor-based nonlinear oscillating circuits and systems were proposed, such as memristive Hindmarsh-Rose neuron model [5], memristive cellular nonlinear/neural network [6], memristive band-pass filter circuit [7], memristive spiking and bursting neuron circuit [8], memristive jerk circuit [9], memristive hypogenetic jerk system [10], memristive hyper-jerk system [11], memristive Twin-T oscillator [12], memristive Chua's circuit [13], memristive canonical Chua's circuit [14], memristive multi-scroll Chua's circuit [15], and memristive Chua's hyperchaotic circuit [16]. However, relatively little attention has been received on the memristorbased Colpitts oscillator [17][18][19]. In addition, the memristive Colpitts oscillator implemented by replacing the bipolar junction transistor with memristor has not yet been reported.…”
