ABSTRACT The current paper demonstrates the design of a wide range differential amplifier using memristor. The paper provides a comparative analysis of traditional approaches with a memristor based approach to achieve a high linear range for an amplifier. The paper also discusses how the inherent nonlinearity of the memristor is helpful in increasing the linear range of an amplifier. A 90 nm operational amplifier design using GenericPDK provided by Cadence Design Systems is used to validate the design and Spectre simulation results are provided as a testimonial to our proposed solution.

    ABSTRACT: In 1971, Prof. Leon Chua proposed and described memristor which defines the relationship between flux and charge. Stanley Williams and his group realized a practical device that fulfills the memristor properties. In this paper, a memristor based high pass filter is presented. A comparative analysis between resistor and memristor based high pass filters is performed. The cut off frequency dependency of the high pass filter with memristor configuration is investigated. SPICE simulation results which are obtained using a memristor SPICE model with nonlinear dopant drift are included to verify theoretical analyses. The effect of change in the input frequency and initial condition of the length of doped region on the cut off frequency of the given high pass filter is investigated. The memory effect of memristor is represented by simulation results.

    ABSTRACT: The memristor has drawn the worldwide attention since it has been discovered at HP laboratory on 1 May 2008. Since then many researchers are taking e®orts to ¯nd its applications in various areas. In this paper, we study the ¯lter characteristics of ¯rst-order low pass and high pass ¯lters employing memristor with a capacitor. The paper provides a comparative analysis between low pass and high pass ¯lter circuits that utilizing ordinary resistor or memristor with a capacitor. The theoretical analyzes are veri¯ed with SPICE simulation results using a memristor SPICE model with nonlinear dopant drift and MATLAB environment. The e®ect of change of the input frequency and initial resistance value of memristor on the cut-o® frequencies of the presented low pass and high pass ¯lters are investigated. The memory e®ect of memristor is represented by simulation results.
