. A half-wave rectifier is needed to supply 15-V dc to a load that draws an average current of 300 mA. The peak-to-peak ripple is required to be 0.2 V or less. What is the minimum value allowed for the smoothing capacitance?

Except for FinFET and GaaFET discussed in the lecture, there are many new designs of FET. Please do a detailed study on any of them. In less than 200 words, state the advantages of it over the traditional

a) With the aid of illustrations and using Silicon, describe what an intrinsic semiconductor material is. (b)  With the aid of illustrations and using Silicon, describe what an extrinsic N type            semiconductor material is. (c)  With the aid of illustrations and using Silicon, describe what an extrinsic P type         semiconductor material is. (d)  With the aid of illustrations, describe what happens when P and N materials are        joined/fused together and what is formed across the join. Then describe and        illustrate how the formation at the junction can be controlled. (e)   Give clear illustrations of characteristics for GERMANIUM and SILICON DIODES and          say what is the threshold value (Vt) for Silicon and Germanium.
