WebFlicker noise dominates the noise spectrum at low frequency. Flicker noise was flrst observed in vacuum tubes over seventy-flve years ago [7]. It gets its name from the anomalous \°icker" that was seen in the plate current. Flicker noise is also commonly called 1=f noise, because the noise WebMay 31, 2016 · To study the low-frequency noise properties of the graphene BR, we have adopted the cross-correlation technique to minimize the noise from the measurement set-up (measurement set-up is shown...
