We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...

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 ...

The schematic diagram shows an audio stage with a common-collector circuit. This does not damp the tuned circuit, but instead actually increases its response. This yields good sensitivity and ...

Once more opto-isolators are to be seen in Wonderland. The aim was to see if the faster photodiode types can operate quickly in common collector mode. They consist of an infra-red led and a fast npn ...

The basic construction of Bipolar Junction Transistor (BJT) comprises of two P-N junctions producing three connecting terminals with each terminal being given a name to identify it from the other two.
