What is the total voltage gain of a high frequency response of differential amplifier if the gain of first stage is 10dB, gain of the second stage is 20dB and gain of third stage is 30dB?

What is the total voltage gain of a high frequency response of differential amplifier if the gain of first stage is 10dB, gain of the second stage is 20dB and gain of third stage is 30dB? Correct Answer 60dB

The total gain of a high frequency response of differential amplifier is the sum of the multiple stages when the gain is calculated is decibels. Given, AV1 = 10dB, AV2 = 20dB and AV3 = 30dB AV = AV1 + AV2 + AV3 = 10dB + 20dB + 30dB = 60dB.
