“…The time-domain impedance, shown in Figure 4B, reproduces the analytical time-domain input impedance of the circuit given by Equation 14. The extracted values of capacitance are C = 30nF ( ≤ Φ) and C = 60nF ( > Φ), matching perfectly the predicted values according to Equation 10. Additional results showing the response of the circuit to a triangular input signal are shown in Figure 4C.…”

“…7,8 In 2009, the concept of passive memory devices was revisited, 9 proposing the memcapacitor and meminductor as a part of a larger essential family of circuit elements for developing a rigorous mathematical theory of nonlinear circuits. 10 The memcapacitance (memory capacitance), C M , that will be the objective of this work, establishes the electrical relation between the time integral of the charge ( ) and the time integral of the voltage (namely, flux, ; see Figure 1):…”

Summary This 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 memcapacitance and the electrical mutation of a memristor. Then, a practical and simple circuit implementation is demonstrated by SPICE computer simulations, circumventing the solid‐state memristor by a two‐state flux‐dependent resistor, which modulates the gain of the amplifier in consonance to the flux of the input signal. Further electrical properties of the system are extracted from its physical implementation in a field‐programmable analog array. The work is concluded illustrating the functionality of the memcapacitor emulator to study neuromorphic applications with a long‐term potentiation example.

SUMMARYMemristor-based technology could be utilized to enhance the performance of many radio frequency (RF)/ microwave subsystems, such as filters. In this paper, we propose that memristors can potentially be used as switches for designing a reconfigurable dual-band RF/microwave planar filter. We are motivated to use memristors instead of some traditional microwave components because memristors do not require any bias, and no moving parts are involved. The reconfigurable filter is designed for multi-band receiver application using only one memristor-based switch. Circuit-level simulations are used to investigate memristor-based RF/microwave circuits and study their performance. The memristive RF switch is modeled by a resistor in the ON state and by a capacitor in the OFF state. An RF/microwave circuit simulator, NI AWR Microwave Office, is used to verify the expected functionality of the proposed memristor-based filter.

“…In the literature, we studied different types of Static Random Access Memory (SRAM) cells like CMOS based SRAM cells [1], Field Effect Transistor (FinFET) based SRAM cells [2,3], Carbon Nanotube FET (CNTFET) based SRAM cells [4], SRAM cell based on Transmission gates [5]. It also gave birth to a new fundamental element, called Memristor [6][7][8] other than the Resistor, Inductor and the Capacitor. Memristor based technology is a new technology that came into the market in order to create non-volatile and low power operated memories of smaller size.…”

Starting from the consecutive properties of Memristor, researchers identify that using a non-linear element "Memristor" into the circuit, the power consumption of the design will be reduced to a great extent. Memristor acts as a conventional resistor, but it has a memory which stores data in the form of resistance. A new Seven Transistors (7T) based Static Random Access Memory (SRAM) cell using memristors is designed in this manuscript that provides low power as well as non-volatile functionality to the cell. Such hybrid CMOSMemristor's combination gives robustness, consistency and higher functionality to the CMOS subsystem. With the proposed 7T SRAM circuit, we observed that the Average Power (0.234 µW), Total Power (10.08 µW), Static Power (20.83 pW) and Dynamic Power (0.01 µW) are reduced over the conventional 7T SRAM circuits. Different low-power optimization tools and device modeling were discovered to make more accurate power consumption calculations. There will be a need of designing such devices which are essential for the VLSI circuit designers. Memristor verifies itself to be a strong contender for the growing demands of Low power and Portable applications. Simulation of the SRAM design has been done in a 45 nm CMOS environment with the help of Cadence Virtuoso tool, and the recorded results depicted the advantages of proposed design over the CMOS based SRAM cell.
