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 ...

CMOS current mirrors are pivotal in modern electronic circuitry, providing accurate current replication that is essential for biasing, amplification and active loading in a myriad of integrated ...

Digital information is usually encoded by controlling the flow of charge carriers, such as electrons, through materials. But a special type of electronics, called spintronics, uses electrons’ spin — ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...

An international group of researchers has developed an electronic device that is said to effectively mitigate hotspots in PV modules. It uses two current comparators, two NPN transistors, and a ...

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 ...
