(C-V) and Y-parameters determination of JFETs under different environmental conditions
The C-V characteristics of n-channel JFET have been measured as a function of temperature up to 140 0C and γ rays up to 100 kGy. The results show that the input capacitance Ciss is increasing function of temperature when measured at low frequency ban
