Question
What is the need of the cascading in the amplifiers? Explain the various coupling schemes used in the multistage amplifiers. Draw a two stage RC coupled amplifier and explain its operation. Discuss the effect of cascading on the bandwidth of the amplifier. A multi stage amplifiers consists of three stages, The voltage gains of the stages are 30, 50 and 80. Calculate the overall voltage gain in 'db'.
