Mobile phones are getting more and more complicated. One reason is that a new radio is needed for each standard-GSM, 3G, and WLAN. A simpler solution, a radio that can be programmed to cover all standards, is now being developed at the Stringent Research Center at Linköping University in Sweden.
“We have come up with three concepts that, together, can reach the goal, the software-defined radio,” says the head of the Center, Professor Christer Svensson.
The three parts are:
The Low-Noise Amplifier and the RF Sampling Receiver Front-End exist already as prototypes in form of functional silicon chips.
Stringent (Strategic Integrated Electronic Systems Research) is Sweden’s largest electronics research center, with more than 50 researchers and graduate students from Divisions of Electronic Devices, Computer Engineering, Electronic Systems, and Embedded Systems. The mission of the Center is to convert complex ideas into silicon, to improve the efficiency of embedded systems, and to reduce developmental times. Basic funding is from the Swedish Foundation for Strategic Research.
The first year of operation has led to many other interesting research results including:

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
