Noise properties of ideal memristors

Autor: Emmanuel M. Drakakis, Itir Koymen, Panayiotis S. Georgiou

Publikováno v: ISCAS

This work investigates how the presence of thermal noise influences the response of simple networks incorporating an ideal memristor. First we study how a single noiseless memristor modulates noise at its input and how it manifests at its output. The
