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 ...

Immediately, I learned that the common base configuration gain was 6db lower than the common emitter. This blew my mind. Then I started checking input resistance and was shocked at how low it measured ...

The common-base configuration is so little used, it doesn’t even register on many engineers’ radar. So, as a self-professed analog guy, I’m embarrassed to say that, while it’s on my radar, I don’t ...

In 2007, a power-conversion startup company was promoting a wall-wart schematic that had an external FET driving an external high-voltage transistor (Fig. 1). I note the startup company has been ...
