The 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...

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 . . .

Modern circuit design is a “mixed signal” endeavor thanks to the availability of sophisticated process technologies that make available bipolar and CMOS (Complementary Metal Oxide Semiconductor), ...
