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: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
