Study Notes
Field-Effect Transistor (FET)
- The concept of a field-effect transistor (FET) was proposed in 1926.
Types of Transistors
- The most widely used type of transistor is not specified.
- Bipolar Junction Transistors (BJTs) use both positive and negative charge carriers.
- Unipolar transistors use only one kind of charge carrier.
History of Transistors
- The first working point-contact transistor was invented in 1947 by John Bardeen and Walter Brattain.
Transistor Structure
- A transistor usually has three terminals for connection to an electronic circuit.
- Voltage or current applied to one pair of terminals controls the flow of current between the other two.
Bipolar Junction Transistors (BJTs)
- Bipolar transistors allow a small current to control a much larger current.
- The regions in a single crystal of material where two p–n junctions are formed are called the base, collector, and emitter.
Integrated Circuits
- Some integrated circuits rely on the field-effect transistor (FET) instead of bipolar transistors.
