Subthreshold Leakage Due to 1/F Noise and Rts(Random Telegraph Signals)

Abstract

An analysis of subthreshold leakage predicts a Gaussian or Normal distribution on large devices but a distorted distribution is possible on small devices. 1/f noise due to RTS signals on large well behaved devices will have a Gaussian distribution and cause a Gaussian current distribution under normal and subthreshold operating conditions. Localized channels or percolation channels can cause a distortion of this distribution and large subthreshold leakage current pulses which are most obvious in small devices.
