Junctions, transistors and the small-signal models used to reason about them before a single number is calculated.

Entries in this section 3 / 9

1. Bipolar Junction TransistorI_C = β · I_B

   A three-terminal current-controlled device in which a small base current regulates a much larger collector current.

2. DiodeI = I_S (e^(V/nV_T) − 1)

   A two-terminal junction that conducts in one direction once the forward voltage exceeds about 0.6 V.

3. MOSFETI_D = ½ k (V_GS − V_th)²

   A voltage-controlled transistor in which an insulated gate sets how much current flows between drain and source.
