An Electronically Tunable Dual Flux Controlled Floating Memristor Emulator

In recent years, memristor emulators have been utilized in a wide range of applications including neuromorphic computing, security, analog signal processing, and other related fields. This article introduces a novel electronically tunable dual flux controlled floating memristor emulator employing single Current Controlled Differential Difference Current Conveyor (CCDDCC), a MOS capacitor, and one PMOS transistor. The core of the suggested emulator features an electronically tunable CCDDCC-based feedback circuit. The proposed circuit avoids passive components, diodes, and analog multiplier circuits. The suggested memristor has the ability to tune the area of the pinch hysteresis loop without altering the input frequency, input voltage, MOS capacitance, and active component. The circuit operates effectively within a 300 MHz frequency range and demonstrates a well-defined pinched hysteresis loop. Its performance is evaluated using 180 nm TSMC parameters, with a compact layout area of 758.12 μm². Additionally, the robustness of the circuit is thoroughly assessed through analyses of temperature variations, supply voltage fluctuations, transistor size variations, and process corner simulations.
