moRFeus – A field-configurable wideband frequency converter and signal generator

MoRFeus is a 30 MHz–6 GHz field-configurable Fractional-N wideband frequency converter and signal generator. Its LCD display and button interface enable dynamic field-level configuration - from switching between signal generator and other modes, to setting the local oscillator frequency and more. It was designed for wideband frequency up- and down-conversion - with an LO frequency range of 85 MHz–5.4 GHz an ...

Laser Beam Wireless Smartphone Chargers: The Next Big Thing

Cellphone chargers have been in existence for years and have grown from one stage to another. It started with the mobile phone traditional charger which had a USB interface, a DC converter, and a charging plug and now has expanded to a close-range inductive wireless charging. The commonly used inductive wireless charging is nice but limited, it still requires close contact with the charging pad making it of ...

How to make precision measurements on a nanopower budget

Heightened accuracy and speed in an operational amplifier (op amp) has a direct relationship with the magnitude of its power consumption. Decreasing the current consumption decreases the gain bandwidth; conversely, decreasing the offset voltage increases the current consumption. Many such interactions between op amp electrical characteristics influence one another. With the increasing need for low power con ...

Use the Force… or Your Brainwaves? (multifuctional Thought Controlled System)

As a kid I always wanted to have a special ability, like moving objects with thoughts or flying. I tried to move objects with “the power of my mind” of course with no success. Well, yes, I was and I am a huge Star Wars fan, but I also like electronics and programming, so why not combine these two things to build an incredible project? You can find all parts, codes and libraries with links at the Hardware an ...

WattUp – RF based Wireless Charging at a Distance

Recently, many big companies such as Samsung have developed wireless chargers which work by induction. These chargers usually consist of a station which needs to be in contact with the device in order to charge. The station defeats the purpose of being able to move and walk while still charging the device. Energeous, a global leader in RF- based wireless charging, created the award-winning device WattUp in ...

Brand New BiCMOS Flexible Transistor

The transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things since its very first practically implemented device as a point-contact-transistor invented in 1947 and getting the Nobel Prize in Physics in 1956. Now, engineers from the University of Wisconsin-Madison (UW-Madison) have built the most flexible, fully-funct ...
