a. What is the use of the Ebers-Moll model in the analysis ofelectronic circuits?(Explain as best as you can)b. Intuitively develop the basic form of the Ebers-Moll modelillustrating it in acircuit diagram sketch. Label your sketch appropriately and brieflydevelopexpressions for the various currents involvedQ2.a. Another class of power electronic devices are junction-gatefield effecttransistors (JFET's)i. Using appropriate diagram (s) sketch the construction of ann-channelJFET.ii. Explain the operation of the JFET sketched in (i) and hencederive thegeneral current-voltage output characteristicsiii. Obtain expression for the channel width, drain current andappliedgate voltageb. A JFET is made by diffusing p+ gates into 0.02 m n-typesilicon. Thedoping in the n-type silicon is 21 3 2x10 m . The gate is 50 mlong and 40 mwide. The zero bias channel width is 5 m. Determine the biasvoltage thatmust be applied to the gate so as to have a channel resistance of10 ?
