Abstract
This research article proposes a floating memristor emulator configuration based on n-type MOSFETs only. The proposed memristor comprises three nMOS and an extra nMOS for an external grounded capacitor. Compared to the existing literature, the proposed floating MOS memristor enables a simple design without any sophisticated design complexity. The actual fingerprint of the memristor as a pinched hysteresis loop with different frequency domains and composite characteristics as incremental and decremental are well examined using computer simulation with 90-nm CMOS technology parameters for MOSFETs. The power consumed by the proposed circuit is <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$2.6~\mu \text{W}$ </tex-math></inline-formula> . In addition, an experimental test using off-the-shelf components is investigated to verify the theoretical and simulated results. Moreover, the proposed nMOS-memristor emulator application is suitable for the modulation and demodulation of binary frequency-shift keying (BFSK) and Boolean logic gates.
