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 . . .

Transistors are an indispensable building block in electric appliances, where they amplify weak electric currents. Now researchers have developed a new type of transistor that is 50 times more energy ...

Power systems and RF designers now have high performance GaN power transistors capable of amplification into the low GHz range. Efficient Power Conversion (EPC) Corporation extended its family of high ...

In recent years, engineers have begun to design and test thermal transistors with some success. Their goal is to exercise the same control over heat that they already have over electric current–the ...

Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...
