Abstract

In this paper, an extensive investigation of low-frequency (1/f) noise and total ionizing dose–response of junctionless accumulation mode double-gate (JAM DG) MOSFET is presented. Current–voltage (Id–Vg) characteristics and low-frequency noise of JAM DG MOSFET are simulated at different ionized doses and compared to different gate oxide thickness and different channel doping concentrations. A significant amount of irradiation-induced threshold voltage shift and increase in low-frequency noise is observed for different gate oxide thickness and channel doping concentration. Moreover, the irradiation-induced border trap densities are also obtained at different doses. The gamma radiation model of Sentaurus TCAD is used to get the required results.
