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.

In previous parts of this series we reviewed the basic transistor parameters that determine ac voltage gain and practical considerations limiting high gain. The role of a coupling capacitor was ...

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 ...
