Sensitivity analysis of memristors based on emulation techniques

Abstract

Memristors are novel elementary passive circuit elements, which behaves like a resistor with memory. Because of their similar functionalities with synapses in human brain, they are well suited for neuromorphic computation circuits. Noisy signals and parameter spreading are common in biological systems. Electronic circuits, including memristors for modeling biological systems, are equivalently exposed with these distortions. Both, noisy signals and parameter spreading can harm the functionality of such memristive circuits. A careful investigation needs reproducible sensitivity analysis with memristors. For this purpose, we use memristor emulators, based on the wave digital method, for sensitivity analysis. With this, we get a reproducible investigation method, which can be used in real circuits, before fabricating the real device.
