Tutorial $-$ Multistage Amplifier

Figure $1$ shows two transistors coupled through the $0\mathrm{.}5F$ capacitor to the input of the second stage $($DC analysis in separate calculation$).$ Assuming that the transistors are identical and have $=150.$

a$.$ Determine the DC analysis for each stage.

b$.$ Find re$1,$ re$2,$ Zi and Zo $.$

c$.$ Redesign the circuit into an AC equivalent circuit.

d$.$ Calculate the voltage gain of each stage.

e$.$ Calculate the overall AC voltage gain for the BJT cascade amplifier circuit.
