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 ...

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).

A design of voltage doubler circuit has been studied in context of electromagnetic energy harvesting using 28 nm FD-SOI technology. After analysis of the operating constraints of the circuit, the ...
