AC coupling is common in amplifier circuits for practical and historical reasons. The practical reason is to remove DC power on a transmission line and into a load. The historical reason is to conform ...

There are several technical features required of capacitors used in professional audio and music applications. High-fidelity and noiseless audio-filtering features are necessary without any compromise ...

This paper presents two approaches to improve the performance of RF low noise amplifiers (LNAs) and downconversion mixers. One approach is for noise enhancement and the other is for improving flatness ...

The idea of transferring energy with water isn’t exactly new. In fact, it’s downright ancient. Running water has been tapped to power our contrivances since folks were getting excited about that new ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Potential sources of RF coupling. How to cut some of the coupling sources. Best practice design to create a system that’s immune to coupling. Wireless system-on ...

It seems like wireless power transfer is all the rage these days. There’s wireless charging mats, special battery packs, heck, even some phones have it built in! And they all use inductive coils to ...
