Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier ...

[Paulo] just tipped us about an Excel based high frequency transistor amplifier calculator he made. We’re guessing that some of our readers already are familiar with these class A amplifiers, commonly ...

This document gives focus on optocouplers including its basic principles, operation, and common applications. Suggested techniques in order to maximize the device’s efficiency are included. Cases ...
