Immediately, I learned that the common base configuration gain was 6db lower than the common emitter. This blew my mind. Then I started checking input resistance and was shocked at how low it measured ...

Just as the common emitter amplifier and common base amplifier each tied those respective transistor terminals to a fixed potential and used the other two terminals as amplifier input and output, so ...

The recent EDN article of Bruce Trump () on the input impedance of an op-amp circuit took into account the single-pole roll-off of its loop gain. He showed with a simple derivation how the equivalent ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

This file type includes high-resolution graphics and schematics when applicable. 1. Bob Pease built this varactor-input op-amp out of discrete components, based on an old design of Jim Williams. A ...

Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many classifications, and each class has its ...

Graphene has already brought us the world's smallest transistor – twice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a ...
