Discussion:
Q: Two identical CE amplifiers are connected in cascade. The first stage is fed with a source vsig having a resistance Rsig = 10 kΩ. A load resistance RL = 10 kΩ is connected to the collector of the second stage. Each BJT is biased at IC =0.25 mA and has β = 100. Each stage utilizes a collector β = 100. Each stage utilizes a collector resistance RC= 10 kΩ
(a) Sketch the equivalent circuit of the two-stage amplifier.
(b) Find the overall voltage gain, vo2/vsig
