(a) Draw the symbol of a p-channel JFET, show its structure with proper biasing shown, and draw the characteristic curve with IDss = 7 mA and Vp = +5 V. Don't forget to indicate its three operating regions on the curve. [2+3+4 marks] (b) Sketch the transfer curve for a p-channel device with IDSs = 12 mA and Vp = 6 V, using shorthand method. Also, determine the drain current ID at VDs = 2 V. [3+2 marks] (c) With the help of diagram discuss the formation of the channel in n-channel MOSFET. [5 marks] (d) Draw the symbols of: [6 marks] 1 n-channel JFET 2 p-channel JFET 3 n-channel Depletion Type MOSFET 45 4 5 n-channel Enhancement Type MOSFET 6 n-channel Enhancement Type MOSFET p-channel Depletion Type MOSFET 7 n-channel MESFET 8 p-Channel MESFET
