The BJT circuit has a current gain β=120, RB=260 KΩ, RC= 5 KΩ, and RE=1.0 KΩ, please find the load line equation and calculate the quiescent values of ICQ and VCEQ; plot the load line and indicate the quiescent point Q on the line. An AC small signal input from the base, the output is from collector terminal. Please draw AC equivalent circuit using hybrid-π model; Please derive the small signal amplification gain. You should show the procedure of the derivation, otherwise, you will lose some points. Find the numerical gain value.
