This problem is AC analysis problem. DC analysis is not needed to answer the question. A) Convert this bias circuit into a bypassed common emitter amplifier that has an output across a load resistor (RL). To do this you should draw three capacitors on the figure below, an input voltage source, and any resistors you think that should be added. B) In the space below the figure, Draw the hybrid t model for this amplifier circuit including all voltages and resistors. Label Vi, Vbe, and vo on the model. Assume the capacitors you add act as short circuits at AC. Be sure to include resistors R1, R2, R3, R4, and RL in the hybrid pi model. > When you "verify" a mode of operation you will need to calculate all three voltages (Vc, Ve, VE for BJTS and VG, Vs, Vo for MOSFETS) and show the correct two conditions are satisfied. > Assume Capacitors acts like open circuits at DC and short circuits for AC. 12V Assume the following: o Beta = 100 O VBE = 0.7 o V: (Thermal) = 26 mV o Vr (Threshold) = 2V O…
