Circuit diagrams often show transistors in switching circuits. For an ideal NPN transistor, the switch-on voltage at the base is typically 0.6V (acceptable range is 0.6V to 0.8V).

All the circuits we worked with in the previous article had the transistor’s emitter taken to ground, took their input from the base, and their output from the collector.

His test circuit uses six 2N2222 transistors to protect the Arduino from excessive current. You can see six red LEDs above which are inline with the base of teach transistor.

Transistor is invented 1947. ... Bardeen and Brattain created an amplifying circuit that seemed to work, using the element germanium They called it the point-contact transistor.

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object ...

Explore a straightforward method to using just one transistor. This clever technique powers small devices with minimal components, making it an efficient and practical solution. Watch as the ...

Researchers have created a simple circuit using transistors that run on the chemicals that control living processes, rather than the electrons that usual transistors use. The result is a step ...

A new technical paper titled “Accelerating OTA Circuit Design: Transistor Sizing Based on a Transformer Model and Precomputed Lookup Tables” was published by University Minnesota and Cadence. Abstract ...
