This article is part of the Ideas for Design Series: Vol. 3, No. 8. This circuit builds on a previous idea in which the addition of an optocoupler to a microcontroller output converted a “dumb” ...

You're probably familiar with the old-fashioned strings of holiday lights that go out completely if one bulb burns out. Although these lights cause hours of frustration during the holidays, they also ...

In many systems, transmission lines drive reactive (mostly capacitive) loads. To preserve signal integrity, you should properly terminate the lines. However, the input impedance of CMOS logic ICs, for ...

Impedance matching is easy if you know the basics. Download the eBook to find out how. During impedance matching, a specific electronic load (R L) is made to match a generator output impedance (R g) ...
