Transistor parameters
A transistor’s parameters represent its electrical properites. Engineers employ transistor parameters in production-line testing and circuit design. A group of a transistor’s parameters sufficient to predict circuit gain, input impedance, and output impedance is also refered to as its small-signal model.
Two-by-two parameter matricies receive designations such as
- T parameters,
- h-parameters,
- z (impedance) parameters,
- y (admittance) parameters, and
- s (scattering parameters).
The tools for designing with transistor parameters include simultaneous equations, determinants, and matrix theory (often studied as part of linear algebra), especially Cramer's rule.
