Just as the common emitter amplifier and common base amplifier each tied those respective transistor terminals to a fixed potential and used the other two terminals as amplifier input and output, so ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...

After discussing the three transistor high-side buck p-mosfet driver (a recognised circuit and not mine) with some of EW’s sage commenters, I wondered once again if I could design something similar ...

An engineer asked me for help when he encountered what appeared to be strange phenomenon while testing a prototype circuit in the system. He saw “mysterious” clipping distortion of the signal at the ...

The use of transistors for switching things ON and OFF is a key feature of proper hacking. The ability for bipolar transistors to turn things ON and OFF is one of the less known uses while transistors ...
