  8. An analytical mosfet threshold voltage shift model due to radiation in the low - dose range has been developed for circuit simulations. experimental data in the literature shows that the model predictions are in good agreement. it is simple in functional form and hence computationally efficient. it can be used as a basic circuit simulation tool for analysing mosfet exposed to a nuclear environment up to about 1mrad. in accordance with common believe, radiation induced absolute change of threshold voltage was found to be larger in irradiated pmos devices. however, if the radiation sensitivity is defined in the way we did it, the results indicated nmos rather than pmos devices are more sensitive, especially at low doses. this is important from the standpoint of their possible application in dosimetry

    該模型物理意義明確，參數提取方便，適合於低輻照總劑量條件下的mos器件與電路的模擬。並進一步討論了mosfet的輻照敏感性。結果表明，盡管pmos較之nmos因輻照引起的閾值電壓漂移的絕對量更大，但從mosfet閾值電壓漂移量的擺幅這一角度來看，在低劑量輻照條件下nmos較之pmos顯得對輻照更為敏感。
