Afterwards, he joined Ericsson where he was in charge of the top-level integration of 4,5 MGate ASICs. From 2003 to 2012 he was with Texas Instruments and was in charge of the development of the CPU for the ultra-low power microcontroller MSP430. Since 2012 he has been working at eesy-ic in the design and verification of different digital modules for mixed signal ASICs. In addition to this, he is responsible for the FPGA implementation of complex systems.

Dr.-Ing. Frank Ohnhäuser

Chief Technical Officer

Dr.-Ing. Frank Ohnhäuser started his career in analog IC development after finishing his studies in Electrical Engineering at the Friedrich-Alexander University of Erlangen-Nuremberg in 1996. At Burr-Brown/Texas Instruments (Tucson, USA), he developed high precision ADCs, and founded and led a development center in Erlangen beginning in 1999 where he was a Senior Member of Technical Staff. He was responsible for product definition of ADCs in the field of industrial applications and IC design and layout as well as the verification, characterization, qualification, and production test of the team’s products. The success was based on customer satisfaction and technical application focus. He currently holds nine patents, has four patent applications, and is author of numerous scientifically recognized publications. He also teaches  the Analog-Digital and Digital-Analog Converters class at the Freidrich-Alexander University of Erlangen-Nuremberg.
