To develop ever-smaller chips that consume less. These are the indispensable requirements of the current market for portable applications such as mobile telephone technology and biomedical systems, obtaining correct and trouble-free operation of the devices over the maximum possible duration of time. One of the techniques which, in fact, can be used for the development of this type of reduced-size, low-consumption microchip is one analysed by Carlos Aristóteles de la Cruz in his PhD defended at the Public University of Navarre. The thesis is titled, “Design and Implementation of Very Low Voltage Square-Root Domain Circuits with On-chip Tuning”.
The SRD (Square-Root Domain) techniques is one of the methods enabling the design of chips or integrated circuits with low power sources, i.e. circuits that can function suitably in those situations where there is a low level of power supply. The technique is based on the design of circuits the internal processing system of which is non-lineal – although the input-output relation is lineal.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
