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 ...

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 ...

Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...

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 ...
