In this paper a new circuit for practical emulation of a floating memristor is presented. The circuit is simple, flexible and built around the current-feedback operational-amplifier and avoids the use of analog-to-digital and digital-to-analog converters and the analog multiplier. The circuit is simpler than the very few available similar circuits. The application of the proposed floating memristor emulator in designing an FM-to-AM converter confirms the functionality of the proposed circuit. Experimental results are included.
