Editor's note: Linear Integrated Systems co-founder, John H. Hall, is an industry veteran who is still hands on when it comes to innovations like the latest JFET, LSK489. Anyone using an electronic ...
Perhaps, that’s the single most popular use for an NPN transistor – driving coils, like relays or solenoids. We are quite used to driving relays with BJTs, typically an NPN – but it doesn’t have to be ...
The converter described below, based on a silicon bipolarjunction transistor (BJT), can operate at as low as 250 mV, which is probably a record for a converter not based on a JFET or germanium ...
