Question:

a) Draw the structure of an n-channel JFET and explain the process of pinch-off when appropriate voltage bias is applied. Why is the depletion layer wider near the drain terminal?

b) Design a universal bias for a CE-amplifier (Fig. 4.11 of your study material) using n-p-n transistor for the following parameter values: $V_{CC}=20\, V,\, V_B=4\,V,\,l_c=10\,mA,\,V_{BE}=0.6V,\,V_{CE}=10V$ and $\beta=100$ Obtain the values of $R_C,R_E,R_1$ and $R_2$ Explain how the Q-point remains stable in this biasing scheme.
