Q1. (80) Consider the BJT amplifier seen in fig. 1. The input AC voltage given by v_(i)(t)=10sin(2\pi 10^(3)t),mV is applied to the amplifier and the AC output voltage obtained is given with the expression v_(o)(t)=-1.2sin(2\pi 10^(3)t). Perform the followings: aA_(v). bA_(v) using the AC equivalent circuit you have drawn in br_(e) in k\Omega . (VT=26 mV at room temperature 27C). eI_(EQ) at operating point Q . Then, determine the value of the DC currents I_(BQ),I_(CQ)\beta =100 a=R(1)/(R)2=29.97, derive an expression for R 2 and then determine the value of R2 and R1 in k\Omega . Find Thevenin voltage VTH and resistance RTH.
