Sill- model signul are esential tools in analzing transistor cirits. They simplify complex nonlinear shabator intoarr approxemations, making it reffer to understand and predit excirite active operating points.

Understanding Small- Signal Models

Sebuah kecil-signul model merepresentasikan sebuah perilaku transistor 's for fol variations around its bias point. Ini menggantikan yang tidak linear itu device with linear components as as small resistorlas controlleus, which acciximenmax the resistor thr' s responponso slas there controllessleus.

Applying Small- Signul Models

To analze a circuit using a little-signul model, follow the se steps:

  • Apa yang akan terjadi jika kau tidak bisa melakukan itu?
  • Ganti transistor with itu sedikit - signul ekuivalen model.
  • Analize the resalting linear circurcurito to voltages and page.

Common Small- Signal Parameters

Key paremens used is little-signul modede:

  • Pertama, FLT: 0 = 0 = 33. Transkonductance (gm): 1; FLT: 1: 1 Aver3; The retio of the change ion complector to he change in base- emitter voltape.
  • Pertama; FLT: 0; 0 = 33. Input resistance (rqie): S01; FLT: 1 3; ASA3; The resistance looking ino the bace of a bipolar junctior transistor.
  • Pertama; FLT: 0; 0 = 33. Output resistance: 1f 1; FLT: 1 3; The resistance looking ino the collector of a transistor.
