10 Nov 2009TL;DR: The memristor as discussed by the authors is the fourth ideal circuit element, which is defined based on fundamental circuit variables, similar to the resistor, capacitor, and inductor, and can be described by any of a variety of time-varying functions.
Abstract: The contribution is concerned on the properties of the new ideal circuit element, a memristor. By definition, a memristor relates the charge q and the magnetic flux in a circuit, and complements a resistor R, a capacitor C, and an inductor L as an ingredient of ideal electrical circuits. The properties of these three elements and their circuits are a part of the standard curricula. The existence of the memristor as the fourth ideal circuit element was predicted in 1971 based on symmetry arguments, but was clearly experimentally demonstrated in 2008. The definition of the memristor is based solely on fundamental circuit variables, similar to the resistor, capacitor, and inductor. Unlike those more familiar elements, the necessarily nonlinear memristors may be described by any of a variety of time-varying functions. As a result, memristors do not belong to linear time-invariant circuit models. A linear time-invariant memristor is simply a conventional resistor.

TL;DR: The Memristor, as the newly discovered fourth circuit element, is being used in many applications such as memory and digital circuits, as well as neuromorphic systems, using a nonlinear mathematical model of physical bipolar memristor devices.
Abstract: The Memristor, as the newly discovered fourth circuit element, is being used in many applications such as memory and digital circuits, as well as neuromorphic systems. The unique characteristics of the memristor: retaining its resistance state, ability to behave as a switch and consequently the possibility to be used in both memory and digital circuits. Its resistance can also change gradually allowing the potential of mimicking neural chemical synapses. These applications of the memristor will be reviewed and discussed using a nonlinear mathematical model of physical bipolar memristor devices.

12 Apr 2012TL;DR: A behavioural model of a memristor and a methodology to perform simulations using the model in memristive circuits are presented and this model can be applied in mixed circuit simulation of memory architectures, neuromorphic circuits and Memristor based analog and RF circuits.
Abstract: This paper presents a behavioural model of a memristor and a methodology to perform simulations using the model in memristive circuits. The model was implemented in Verilog-AMS and simulated in Mentor Graphics Eldo with AMS support. A case study of a memristive cell is presented to validate the model in a mixed circuit containing memristor model and SPICE components. This model can be applied in mixed circuit simulation of memory architectures, neuromorphic circuits and memristor based analog and RF circuits.

21 Jun 2017TL;DR: An amplifier circuit whose magnification is precisely adjustable and an active memristor-filter whose cut-off frequency and phase are adjustable as well is presented, which provides a new way for the integrated circuit design in the future.
Abstract: Based on the electrical properties of memristor, the spintronic memristor is introduced into analog circuit design. Through programming the memristor by pulse signals, a programmable memristor potentiometer is designed in this paper. The potentiometer has the advantages of simple structure, small volume and continuous variable dynamic range. Based on the potentiometer above, this paper presents an amplifier circuit whose magnification is precisely adjustable and an active memristor-filter whose cut-off frequency and phase are adjustable as well. The circuit is characterized with smaller size, higher integration and lower power consumption, and its correctness and feasibility are verified by SPICE simulation. The research in this paper will promote the application of memristor in analog circuit, in addition, the performance of programmable memristor-analog circuit is satisfactory, which provides a new way for the integrated circuit design in the future.

TL;DR: The investigations depict good agreement with the conventional lumped component based phase shift oscillator, integrator, and differentiator circuits and showcase the potential of the memristor as a promising candidate for the next generation analog circuits.
Abstract: In this paper, we investigate few memristor-based analog circuits namely the phase shift oscillator, integrator, and differentiator which have been explored numerously using the traditional lumped components. We use LTspice-IV platform for simulation of the above-said circuits. The investigation resorts to the nonlinear dopant drift model of memristor and the window function portrayed in the literature for nonlinearity realization. The results of our investigations depict good agreement with the conventional lumped component based phase shift oscillator, integrator, and differentiator circuits. The results are evident to showcase the potential of the memristor as a promising candidate for the next generation analog circuits.
