Solid-State Memcapacitors and Their Applications
2014This chapter introduces the concept of a memcapacitor, and reviews different approaches to its physical realization. Also, practical constraints for their usage are assessed. Because of their compatibility with traditional circuit integration technologies, two approaches are particularly interesting: the ferroelectric capacitor and the memcapacitor ...

Chaos in a memcapacitor based circuit
2014 IEEE International Symposium on Circuits and Systems (ISCAS), 2014The memcapacitor has the potential to be the most useful new component of recent years due to its functional and dynamic similarities to the memristor but with much lower power requirements. Although research interest is growing, there are very few memcapacitor based circuits.

Mutators simulating memcapacitors and meminductors
2010 IEEE Asia Pacific Conference on Circuits and Systems, 2010Whereas the memristor can be emulated via digital potentiometer controlled by a microcontroller, a similar implementation of memcapacitor and meminductor is problematic. The paper describes a synthesis of mutators which transform the emulated memristor into memcapacitor and meminductor.

Memcapacitor based charge pump
2017 6th International Conference on Modern Circuits and Systems Technologies (MOCAST), 2017This paper proposes a charge pump based on a charge controlled memcapacitor. The operation of the charge pump is investigated along with the mathematical analysis of the memcapacitor. Different implementations of charge pump are summarized. The proposed charge pump has the capability of driving low input voltage in range of 200mv and the capability of ...

Organic thin film memcapacitors
Applied Physics Letters, 2019Organic thin film memcapacitors are designed and implemented by an organic multilayered structure, consisting of a semiconducting carrier accumulation layer and a polymer electret charge trapping layer. The capacitive states of the device can continuously and reversibly change upon programming/erasing at high biases, whereas they show nonvolatility ...

Memcapacitor emulator based on the Miller effect
International Journal of Circuit Theory and Applications, 2019SummaryThis work provides the guidelines to design and implement an elemental memcapacitor circuit emulator based on the relation between memcapacitance and the Miller effect in voltage amplifiers. The emulator is presented theoretically in a top‐down approach, from the circuit behavior to the foundations of the constitutive equations of the ...

Memcapacitor Based Applications
2015This chapter is divided into three sections focusing on some memcapacitor-based applications. The first one discusses the mathematical analyses and design of resistive-less memcapacitor-based relaxation oscillators where different cases have been investigated and validated. Analytical expressions for the oscillation frequency, duty cycle, stored energy,

On the mathematical modeling of memcapacitor bridge synapses
2014 26th International Conference on Microelectronics (ICM), 2014Mem-element based synaptic bridge is very promising topic due to its learning capability where the synaptic bridge can be build using either memristors or memcapacitors. In this paper, the detailed mathematical analysis of memcapacitor bridge circuit is introduced. This mathematical analysis is build when a current input signal is applied to excite the

A nonlinear circuit with two memcapacitors
Nonlinear Dynamics, 2016In this paper, a circuit with two memcapacitors is designed, and the dimensionless mathematical model of the circuit is established. We find three kinds of chaotic attractors in this circuit. Using the conventional dynamic analysis method, the equilibrium points and stability of the chaotic system are analyzed, and the distribution ranges of stable and
