CE Amplifier Small-Signal Equivalent Circuit

Click For Summary
SUMMARY

The discussion focuses on deriving the small-signal equivalent circuit for a CE amplifier, specifically addressing node analysis at node E. The participant successfully derived nodes B and C but encountered difficulties with node E. It was noted that the term Vc/Rc was omitted from the equation for node E, which is critical for accurate analysis. The use of Microsoft tools was mentioned to illustrate the steps taken in the derivation.
