Problem 3: Design Problem On Figure P3a, you have a Common Source (CS) n-channel MOSFET amplifier. Notice the absence of a source resistor Rsig and load resistor R. If we know how the present amplifier (the one on Figure P3a) behaves without Rsig and RL, we can infer its behaviors if Rsig and R were to be added. design the amplifier circuit on Figure P3a, i.e., you have to find appropriate values for RGj You are to RG,, RD, and...
