Two-stage Amplifier: An amplifier has a first stage with a voltage gain of 34.3 and a second stage with a voltage gain of 115. If the ac input voltage to the first stage is 0.628 mV, what is the total voltage gain and the ac output voltage?
Answer: The total voltage is the product of the stage gains, which is approximately 3930 (allowing for computer rounding error). The ac output voltage is 2.47 V.
