Study Notes
- Transistor is a semiconductor device used to amplify or switch electronic signals and power.
- It is composed of at least three terminals for connection to an external circuit.
- A voltage or current applied to one pair of terminals controls the current through another pair of terminals.
- Transistors can amplify a signal, with the output power being greater than the input power.
- They are the fundamental building blocks of modern electronic devices.
- The first transistor was invented in 1947 by John Bardeen, Walter Brattain, and William Shockley at Bell Labs.
- They were awarded the Nobel Prize in Physics in 1956 for their discovery.
- Transistors are made of pure silicon or germanium, but other semiconductor materials can also be used.
- Compared to vacuum tubes, transistors are smaller and require less energy to operate.
- The invention of the transistor is considered one of the greatest inventions of the 20th century and is a key component in modern electronics.
- Transistors were first invented in 1947.
- They are used to amplify and switch electronic signals.
- Transistors were initially produced individually, but are now mostly produced in integrated circuits (ICs).
- ICs include other electronic components such as diodes, resistors, and capacitors.
- A logic gate consists of up to 20 transistors, while a modern microprocessor can use up to 3 billion transistors.
- In 2002, 60 million transistors were built for every person on Earth.
- Transistors revolutionized the field of electronics and enabled the development of modern technology.
- They are essential components in computers, smartphones, and many other electronic devices.
- The invention of transistors led to the decline of vacuum tubes, which were larger and less efficient.
- The first transistor was made of germanium, but silicon is now the most commonly used material.
