A silicon semiconductor resistor is in the shape of a rectangular bar with a cross sectional area of 1x10-6 cm2 a length of 0.1 cm and is doped with a donor concentration of 5x1016 cm-3.(a) Calculate the resistance of this resistor at 300K. The mobility is 1100 cm2/Vs(b) Calculate the current in the resistor if a bias of 5 volt is applied across the length of the device.(c) What is the average electron drift velocity?
Using 4 PSK or 2 PSK with the same total power as a reference, calculate the Eb/No versus Pe waterfall plot and compare the asymptotic coding gain of the coder/encoder.
