AC testing of electronic ... then amplifies the signal and drives the load. While the potentiometer will work, it will not provide automatic gain control; you can get that if you replace the ...

Also, a single power MOSFET is only capable of switching a DC voltage since its internal source-drain diode will become forward biased if the load polarity is reversed. Using a PhotoMOS relay for ...

If you open up the perennial favourite electronics textbook The Art Of Electronics and turn to the section on transistors ... signal such as our sine wave. The classic simple transistor AC ...

The holiday gave me a chance to play with bipolar transistor mosfet drivers again. And things did not go quite as planned. I had been using the circuit on the right quite happily from a signal ...
