Transistor as an Amplifier — Study Resources & PYQs
Application of a transistor as an amplifier.
- Estimated study time: 30 minutes
Study resources
- Introduction to Bipolar Junction Transistors (Article) — Explains the BJT as a current-controlled current regulator, then the sidebar leads to separate pages for common-emitter, common-collector and common-base amplifiers with worked analysis.
- Chapter 4: Bipolar Junction Transistor - Neso Academy (Video) — Covers the amplifying action of the CB and CE configurations directly.
- 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).
- Bipolar junction transistor (Wikipedia) (Article) — Reference on the BJT's structure and symbol (NPN/PNP), its current-voltage characteristics, and how it is used as a switch or as a current/voltage amplifier.
- Basic Electronics - Prof. M.B. Patil, IIT Bombay (NPTEL), curated by Class Central (Video) — NPTEL video course whose early weeks work through diode circuits and diode rectifiers in detail, followed by the physics and amplifier circuits of the bipolar junction transistor.
