Week 02
Diode Models and Load Lines
I organize a study path from diodes to single-transistor amplifiers in the order that makes the circuit behavior easiest to revisit.
What I connect in this unit
The ideal diode supplies a switch-level approximation, the constant-voltage model includes a forward drop, and the exponential characteristic describes current variation. Intersecting that curve with the load line locates the operating point.

Technical anchor
For a series resistor, the load line is ID = (VS − VD)/R; its intersection with ID = IS(e^(VD/nVT) − 1) is the quiescent point.
How I review it
For the same VS and R, compare predicted VD and ID from the ideal, 0.7 V constant-drop, and exponential models.
