An amplifier has three stages. A differential input stage drives a gain stage followed by an output stage. Each stage of the amplifier has a frequency response which can be shown to be equivalent to a first order low pass filter with gain. The gain of the differential stage is 20 dB and the cut-off frequency is 100k rad/sec. The gain of the gain stage is 60 dB and the cut-off frequency is 10k rad/sec. The output stage has a gain of 10dB and a cut-off frequency of 1000k rad/sec.. For the circuit shown in Figure B2, show that the voltage gain A, is Z2 (Z3+ Z4) Z3(Z₁ + Z₂) A₂

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.
