TL;DR: In this article, an improved SPICE model of memristor using dependent sources and switches is presented. But the model is not suitable for wireless communication and its performance in frequency and amplitude has not been evaluated.
Abstract: This paper introduces an improved SPICE model of memristor using dependent sources and switches. The proposed SPICE model with two parameters in dependent current source has ideal frequency and amplitude characteristics. We simulate two circuits with memristor. The results demonstrate that the memristor can “remember” last resistance value when no current passes through it, the Amplitude Modulation (AM) circuit with memristor and op-amp is simulated under the condition of high frequency. Since the memristor has great performance in frequency there might be a possible application of the memristor to be used as modulator or demodulator in wireless communication.

TL;DR: This paper presents a Memristor base 4-bit digital-to-analog convertor using a single input programmer consisting of a DeMultiplexer and a reset switch to adjust memristance of memristors.
Abstract: This paper presents a Memristor base 4-bit digital-to-analog convertor. A single input programmer consisting of a DeMultiplexer and a reset switch is used to adjust memristance of memristors. By using this programmer, memristances value is reached to the targets value with maximum error of ±1%. The proposed DAC achieves a DNL (differential nonlinearity) and an INL (integral nonlinearity) of 0.075 LSB and 0.123 LSB, respectively.

TL;DR: In this article , an emulator using DVCC and OTA analog building blocks to emulate memristive behavior was proposed, which works in incremental and decremental mode and operates up to 8 MHz.
Abstract: In this article, we have proposed an emulator using DVCC and OTA analog building blocks to emulate memristive behavior. Along with OTA and DVCC, one resistor and one capacitor are used in the memristor emulator. The presented memristor emulator works in incremental and decremental mode and operates up to 8 MHz. The proposed memristor emulator is simulated using PSpice with a 180 nm CMOS parameter. The flexibility of the memristor is tested by simulating it at different temperatures. The adaptability of the memristor emulator during circuit implementation is tested by connecting the memristors in parallel.

TL;DR: In this article, tungsten-oxide-based memristors compatible with CMOS-based neuromorphic circuits are reported, where memristor crossbar arrays are fabricated on partially-processed wafers from a CMOS foundry to form hybrid FET-memristor circuits.
Abstract: We report a fabrication process and electrical results for tungsten-oxide-based memristors compatible with CMOS-based neuromorphic circuits. Memristor crossbar arrays are fabricated on partially-processed wafers from a CMOS foundry to form hybrid FET-memristor circuits that can serve as analog memory elements for synaptic weight storage. Successful integration is demonstrated through the programming and reading of memristor crossbar array elements addressed through a CMOS multiplexer/demultiplexer.

TL;DR: In this article, a DC circuit model of TiO2 memristors is developed based on the reported I-V data, which can be easily implemented to realize memristor based circuitries that serve different application platforms fabricated using any material combination.
Abstract: DC circuit model of TiO2 memristors is developed based on the reported I-V data. The method described can easily be implemented to realize memristor based circuitries that serve different application platforms fabricated using any material combination. The time varying length of conductive filaments inside memristor, responsible for the observed switching mechanism, is implemented as the state variable and the state equations are modified accordingly. Once the device physics is taken into account the circuit model can be further adapted to predict the behavior of memristor with altered dimensions.
