Single VDTA Based Grounded Memristor Model and Its Applications

An application-based memristor prototype by employing only a single Voltage Difference Transconductance Amplifier (VDTA) as an active device and one grounded MOS-capacitor is reported in this research article. The transient analysis, pinched hysteresis loop for various frequencies along with serial and parallel combinations of the memristor are also examined. This grounded memristor design can suitably operate up-to MHz ranges. As an application of the stated memristor prototype, demodulation of grounded memristor-based Binary Frequency Shift Keying (BFSK), Amplitude Demodulation and a realization of Schmitt trigger configurations are shown. Moreover, the layout of this memristor is performed which occupies an effective area of 1432μm
