Design a three-stage amplifier that is impedance matched (use an emitter follower in stage 2) with an overall voltage gain of approximately 400. The phase of the input and output signal should be maintained. The amplifier should have a usable bandwidth of approximately 20MHz. As engineers you are expected to provide mathematical calculations, circuit diagrams and simulations in multisim software. The simulations should show a sample input signal, its output signal and frequency response plot of the three-stage amplifier.
