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 ...

Biasing an active device, such as a bipolar junction transistor (BJT), requires that you set the dc voltages and currents of the device. To optimize the desired result, you need various bias values.

The transistor has been around since the nineteen forties. In fact, the FET (Field Effect Transistor) was actually developed before the more common bipolar type. Bipolar transistors use semiconductor ...

Your design task, should you decide to accept it: given an input voltage, square it. Ok, that’s too hard since squaring 8 volts would give you 64 volts, so let’s say the output should be 10% of the ...

There is some hogwash out there, masquerading as engineering white papers, which are really just click bait to get your contact details. And there are some gems available for the same price. And, in ...
