The power stage of switching converters can be modeled essentially as a PWM-switch. A switch seems to be far from the kind of circuit element that can be linearized, but it can be. This Part 2 ...

Here are the 2 simple circuits named clap switch circuits which are based on clapping. These circuits are useful in switch ON/OFF any devices by just clapping without any movement from your place.

Replay: Transistors are, literally, a miracle. Phil Rhodes recently looked at how they work. Now, let's see where they're going to take us. I feel I have a special connection with technology. It might ...

According to the U.S. Department of Energy, the electricity used to light businesses represents 25% of the energy they spend, so it's important to develop energy-saving devices. Now engineers at the ...

I needed a simple LED indicator showing that a particular voltage level had been reached—specifically, that a capacitor had charged to a particular potential. I was convinced that there must be a way ...
