Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Amplifiers with internal voltage clamps, also known as limiting amplifiers, have a wide range of practical uses. They are most commonly used to protect load circuitry that has a limited input range.

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

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 . . .

The automobile is a tough venue for today’s electronics. Supply voltages can range from 12 to 16 V, depending on battery charge state. On top of that are the spikes and ac noise coming out of the ...
