Q6: Determine the voltage gain and power gain of the Class A power amplifier in the following figure. Assume ac=200 for all transistors.
Sri K.
The amplifier shown in Fig 2 has an output power Pout = 100mW. The voltage gain Ay in dB is approximately equal to: Fig 2 54 dB 10 dB 500 dB

(a) For the circuit shown in Fig. $5.53,$ show that the gain is $$\frac{v_{o}}{v_{i}}=-\frac{1}{R}\left(R_{1}+R_{2}+\frac{R_{1} R_{2}}{R_{3}}\right)$$ (b) Evaluate the gain when $R=10 \mathrm{k} \Omega$ $R_{1}=100 \mathrm{k} \Omega, R_{2}=50 \mathrm{k} \Omega, R_{3}=25 \mathrm{k} \Omega$
