Abstract

The influence of random telegraph noise (RTN) in MOSFETs on drain current (I_d) during the rise/fall edges of the pulsed gate voltage (V _g) cycle was investigated. We have revealed for the first time that the existence of RTN increases I_d fluctuations under dynamic V _g by making a comparison between FETs with and without RTN. The initial trap occupation states before varying V_g, which are governed by the RTN profiles, significantly affect the I_d values during the rise/fall edges of V_g. The revealed effects of RTN with different profiles on I_d under dynamic V_g will be useful for designing ultrahigh speed circuits.
