For applications that require or desire a computer controlled variable current, the use of a digitally controlled potentiometer and a current mirror with degeneration provides a low cost solution. One ...

Circuit and system design requirements often mean compromises. For example, optoisolators are used almost everywhere, but they are highfrequency limited. This simple circuit allows for wider bandwidth ...

Using CMOS gates to generatepulses sometimes causes timinguncertainty due to gate-threshold variations.For accurate pulse widths, youcan use BJTs (bipolar-junction transistors).Basing the design on ...

Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...

If you've ever designed an RF oscillator, you've probably encountered squegging. Sometimes called "motor boating," squegging causes oscillators to start and stop at frequencies much lower than the ...

In analog layout design, precise layout matching techniques are crucial to ensure the accuracy and performance of the circuit so that transistors exhibit similar electrical properties (i.e.

Analog integrated circuits (ICs) are used to control and regulate conditions such as temperature, speed, sound, and electrical current. In analog ICs, voltage and current vary continuously at ...

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 ...

Transistors are tiny electronic components that act as switches and amplifiers, and they dwell at the heart of modern technology. In simple terms, a transistor can turn a flow of electricity on or off ...
