”As part of the BMBF joint project named KD Optimi, IMMS as subcontractor to CiS developed three customized integrated circuits, with which we at CiS hope to extend our range of optoelectronic microsystems products for industrial applications.

The IC produced by IMMS will, because of its transimpedance amplifier (adapted to the CiS photodiodes), evaluate the flow of current in individual photodiodes or small arrays, so that it can be used for variety of applications. The LED driver ASIC developed by IMMS has extended our ability to stabilise and control the brightness of LEDs. The third circuit provided by IMMS is an evaluation IC for a silicon photomultiplier and will enable tiny light signals to be evaluated, even down to single photons.

The cooperation with IMMS ran extremely smoothly. The colleagues were spot on and worked with efficiency, so that they produced the designs for the first two ICs within the shortest possible time and passed the design over for manufacture. The ASICs produced functioned according to specifications in the first design, as IMMS was able to confirm in its measurements. Both ASICs are being installed by CiS, both operate reliably and both have been presented by us to knowledgeable customers at trade fairs such as compamed 2013.

At the end of 2013, it was the turn of the newest Optimi IC to be tackled: IMMS sent this on to the manufacturing stage at the beginning of 2014. As the project has gone so well up to now, we fully expect that this ASIC, too, will enjoy the same success as the first two which were developed. Our aim is to collaborate even more intensively with IMMS in the future.“
