|Abstract:||The low-frequency noise power spectrum of small dimension MOSFETs is dominated by Lorentzians arising from Random Telegraph Signals (RTS). The low-frequency noise is observed to decrease when the devices are periodically switched �off�. The amount of noise reduction is observed to be dependent on the amplitude of the switching gate signal. The time-domain technique of determining the statistical lifetimes and amplitudes of the RTS by fitting the signal level histogram of the time-domain record to two-Gaussian histograms is used for analysing the �noisy� RTS along with the device background noise. The device background noise or 1/f noise of the device can then be separated from the RTS using this procedure. In this work, the RTS and the corresponding 1/f noise observed in MOSFETs, under both constant and switched biased conditions, have been |
investigated. Also, the noise reduction as a function of gate-switching amplitude during switched biased conditions is investigated.
