Analyse the amplifier circuit in Figure 9. The h_(FE) is 75,V_(BE(on))=0.7V and V_(T)=25mVI_(CQ),V_(CEQ) A_(V)=(V_(out ))/(V_(in )). Sketch the output waveform with respect to the input.
d. How would you redesig(n)/(m)odify this circuit to increase the voltage gain?
7 marks + 3 mark Analyse the amplifier circuit in Figure 9. The h_(FE) is 75,V_(BE(on))=0.7V and V_(T)=25mV.
a. Determine the Q -point (I_(CO),V_(CEQ)).
b. Determine the hybrid-pi parameters and draw the small signal model.
c. Find the voltage gain A_(V)=(V_(out ))/(V_(in )). Sketch the output waveform with respect to the input.
d. How would you redesig(n)/(m)odify this circuit to increase the voltage gain?
