OTA based high frequency tunable resistorless grounded and floating memristor emulators

In this paper, a new design has been proposed for the realization of grounded and floating memristor emulators built with two OTAs and one grounded capacitor. The proposed emulators can be configured in both incremental and decremental topology. This paper also proposes the application of memristor as Amplitude Modulator (AM). The proposed circuit and its application claim that the circuit is much simpler in design and can be utilized in both topologies. The performance of all the proposed circuits has been verified with Cadence Virtuoso Spectre. Furthermore, post-layout simulations and its comparison have been carried out. Moreover, experimentation of the circuits has also been performed and found satisfactory results.
