We love the WS28xx projects because even if we never plan to use them, the signal timing is like the most addictive puzzle game ever. For instance, check out this WS2811A driver which uses hardware ...

The holiday gave me a chance to play with bipolar transistor mosfet drivers again. And things did not go quite as planned. I had been using the circuit on the right quite happily from a signal ...

Your design task, should you decide to accept it: given an input voltage, square it. Ok, that’s too hard since squaring 8 volts would give you 64 volts, so let’s say the output should be 10% of the ...

The circuits were designed using a single IC L200 to create two different regulators where one circuit functions as high current regulator using NPN pass transistors while the other circuit functions ...

Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs can ...

In 1964, when I started working in the electronics industry, a single silicon transistor cost over £1 ($2.80 at the time, or about $22 at 2014 prices). These cheap ones were not very good and higher ...
