The transistor is probably the most important invention in electronic engineering and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic device that can ...

I was digging around in the LM311 (and LM111, LM211) comparator data sheet, and came across this unusual voltage reference (diag right). It consists of an npn cascsode pair of transistors, the top one ...

A mixer is a special type of electronic circuit that combines two signals (periodically repeating waveforms). Mixers find a lot of use in audio and RF systems and rarely used as simple analog ...

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

The 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...

In the world highly affected by pandemic there is a huge spike in covid infection cases. With limited resources this fight against Covid 19 virus is an unexpected challenge for the whole world. At ...
