Small instrumentation amplifier for high density arrayed sensor devices

Small-area, low-power, low-noise instrumentation amplifiers (IA) are critical components of arrayed sensor devices used for high-spatial-resolution biomedical and environment monitoring system.
However, in order to realize small offset voltages of IA, conventional IAs utilize analog filters¡ªcomposed of large passive components, resistors and capacitors¡ª resulting in excessively large silicon chips.

Now, Ippei Akita and colleague at Toyohashi University of Technology have developed a novel architecture for fabricating smaller sized integrated circuit chips. The technique is based on a digital calibration scheme for minimizing the offset voltage of the IA circuit, instead of an analog scheme used in conventional circuits.

The offset exists mainly at the first-stage circuit of IA. In this design, the researchers introduced a reconfigurable first-stage circuit. The best configuration for minimizing the offset was easily determined by calibration logic which was implemented in a small area compared to analog circuits.

The proposed IA was implemented in a standard 0.18 micrometer CMOS and resulted with an offset voltage of
The researchers plan to use the proposed IA for the fabrication of an arrayed IA for high-spatial-resolution and real-time sensing systems.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Studying fundamental particles in materials

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
