Transistor Definition
A transistor is defined as a semiconductor device used to amplify or switch electronic signals.
Types of Transistors
There are two main types of transistors: Bipolar Junction Transistors (BJTs) and Field Effect Transistors (FETs).
BJTs
These are current-controlled devices with three terminals (Emitter, Base, Collector) and can be further classified into various types like Heterojunction Bipolar Transistors and Darlington Transistors.
FETs
These are voltage-controlled devices with three terminals (Gate, Source, Drain) and include types like MOSFETs and High Electron Mobility Transistors (HEMTs).
Function-Based Types
Transistors can also be classified by their function, such as Small Signal Transistors for amplification and Power Transistors for high power applications.
