Eleazar Falco, FAE, Würth Elektronik eiSos / Editor, Gerhard Stelzer

Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design. The flyback converter is an isolated switching power

Augmented Reality and the Internet of Things

James Colby, Manager of Business Development, Littelfuse, Inc.

For those of us who wear glasses for vision correction, we are used to seeing the world through lenses. However, new technologies will allow a virtual world to be laid on top of the real world that we normally see. In other words, the lenses will become displays that allow us to see the “real” world th

A Plug 'n Play Linearizer for Your 5G RF Power Amplifier

Thomas Maudoux & Michael Jackson, Maxim Integrated

‘Mar’s Law’ presents a tongue-in-cheek perspective on how data measurements can sometimes be manipulated to fit a more linear profile than is the reality. However, there are no such shortcuts to achieving high linearity for a power amplifier (PA), which is at the heart of mobile cellular communication in
