Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

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 ...

Emphasizing operational amplifiers and integrated devices used in digital circuits, this text presents a thorough discussion of state-of-the-art electronic devices.

In this section, we will discuss numerous transistor bias circuits. So far we have only shown how to design the microwave portion of the amplifiers. We have not shown how the low-frequency part of the ...

The final part of this series will start with bias servo circuits for automatic set up. The FETs pinch off or threshold voltage can vary widely for the same part number. Depending on the fabrication ...

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 ...

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 ...
