- Estimated study time: 30 minutes
Study resources
- The Bipolar Junction Transistor (BJT) as a Switch (Article) — Shows the difference between biasing into the linear region (amplifier) and into saturation and cut-off (switch), with a lamp-driver example. The saturation vs cut-off distinction is the exam answer.
- Neso Academy - Analog Electronics: BJT AC Analysis (Chapter 6) (Video) — Chapter 6 of the playlist explains how the same BJT is operated in the active region to amplify signals and in cut-off/saturation to act as a switch.
- GeeksforGeeks - BJT Amplifier: Types, Working Principles and Formulas (Article) — Explains the active, saturation and cut-off regions of a BJT and how each is exploited for amplification (active region) versus switching (cut-off/saturation).
