In the late 1990s I was working for a company that manufactures sub-systems for tramways, subways and light rail car manufacturers. One day my boss tells me that one of our inverters, a 5 kW DC to ...

This simple circuit has helped me out on many occasions. It is able to check transistors, in the circuit, down to 40 ohms across the collector-base or base-emitter junctions. It can also check the ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...

Using a multi-shunt-based current-monitoring circuit with a 50-MHz op amp delivers an overcurrent detection response time of ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...
