two identical CE amplifiers are connected in cascade. The first stage is fed with a source eVsig having a resistance Rsig= 10k ohms. A load resistance Rl=10K ohms and is connected to the collector of the 2nd stage. Each BJT is biased at Ic= .25mA and has beta =100 and a very large Va. Each stage utilizes a collector resistance Rc=10K ohms.
(a) Sketch the equivalent circuit of the two stage amplifier.
(b) Calculate the voltage transmission from the signal source to the input of the first stage.
(c) Calculate the voltage gain of thefirst stage, Av1.
(d) Calculate the voltage gain of the second stage, Av2.
(e) Find the overall voltage gain, Vo2/Vsig.
