Part 9: Half-Circuit Analysis & Gain of Differential Amplifiers (BJT Explained)

In this Part 9 of the Differential Amplifier series, we break down one of the most powerful analysis tools in analog design — the half-circuit method. You’ll learn how a BJT differential amplifier can be simplified into two identical half circuits, making it much easier to understand and calculate differential gain. In this video, we cover: What the half-circuit concept means in differential amplifiers Why symmetry allows us to split the circuit Deriving half-circuit gain step-by-step Relationship between half-circuit gain and overall differential gain Intuition behind emitter resistance and transconductance effects
