If you open up the perennial favourite electronics textbook The Art Of Electronics and turn to the section on transistors, you will see a little cartoon. A transistor is shown as a room in which ...

You would like to measure the output pin of your circuit with a spectrum analyzer, but the pin needs to be biased to be in a standard operation mode. How would you bias this circuit without affecting ...

Bias circuits for class AB buffers (Fig. 1a) can take several forms. One alternative (not necessarily the best) is usually called the “old VBE doubler” (Fig. 1b). The main purpose of these circuits is ...

The use of digital potentiometers and volume-control ICs to replace mechanical pots enables a wider variety of user-interface features, but consumer-product designers are also pushed to reduce costs ...

An N-channel JFET has a low bias current when its gate is biased negative to the source. However, this requires either that the gate voltage be biased negative with respect to the source voltage or ...

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 ...
