CMOS-based nanopower memristor dynamics emulator

An active weak-inversion CMOS-based memristor emulator is proposed. The circuit is composed of a grounded capacitor and two log-domain exponential transconductors (E cells). It consumes a few nanowatts of power from a 1V power supply. Simulation results confirm the realisation of pinched hysteresis loops characterised by the zero crossing property of the memristor. The effects of varying capacitor values and varying input amplitude and frequency are also simulated. The simple emulator presented here offers the possibility of realising memristor dynamics when high yield memristor processes are not accessible.
