Solve the following problem:
Q: Consider the CE amplifiers of Fig. for the case of I =0.5 mA, β =100, and VA =100 V. Find Rin , Avo, and Ro. If it is required to raise Rin by a factor of 5 by changing I, what value of I is required, assuming that β remains unchanged? What are the new values of Avo and Ro? If the amplifier is fed with a signal source having Rsig = 5 kΩ and is connected to a load of 100-kΩ resistance, find the overall voltage gain, vo/vsig.
