Abstract :
In this paper, a flux-controlled memristor emulator with floating terminals by making use of four current conveyors is newly proposed. By replacing the three resistors in the positive and negative feedback loops of a typical relaxation oscillator respectively, three cases of memristor emulator based oscillating circuits are theoretically constructed and mathematically analyzed. To further probe the practicability and inherent features of the new memristor emulator and oscillator, experimental tests are carried out and the measured experimental results show differences from typical relaxation oscillators, this new memristor emulator based oscillator can provide novel and steady oscillating behaviors. The comparison of measured data with theoretical analysis is in good agreement, which further confirms the practicability of this new memristor emulator and oscillator.
