Smart minds for a strong team

Our experienced employees


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.

Managing Director

Andreas Rother has many years of experience in corporate management, finances and business administration. His core competencies are development of growth-oriented organizations, reorganization of businesses and creation of necessary control systems and processes. Furthermore, Mr. Rother is founder and shareholder of QuarterMill Technologies GmbH.




Dipl.-Ing. Andreas Wickmann

Competencies: Design and layout of analog integrated circuits for power management and signal processing.

Experience: Andreas Wickmann graduated as an Electrical Engineer from the Friedrich-Alexander University Erlangen-Nuremberg, Germany in 2008. He began his career at Texas Instruments, Germany where he was an Analog Design Engineer from 2008 to 2012 developing 16-bit SAR A/D converts and isolated amplifiers for current shunt measurement applications.

In 2012, he joined eesy-ic Ltd, where he has been involved in the design of low-voltage/ ow-power analog circuits. Mr. Wickmann holds three patents in circuit design of data converters and has published several technical papers. Since 2011, Mr. Wickmann has been teaching Analog IC Signal Conditioning at the Friedrich-Alexander University of Erlangen-Nuremberg dealing with the design of the integrated analog circuits.

Mixed Signal-IC; IC-Verification & Characterization

Dipl.-Ing. Michael Reinhold

Competencies: Design and layout of mixed-signal integrated circuits such as data converters and isolation

Experience: Michael Reinhold has 20 years of professional experience in delopment of integrated circuits (Fraunhofer Institute for Integrated Circuits and Texas Instruments). His experience lies primarily in the specification and the development of analog and mixed signal integrated circuits. Examples of his work include: 


  • ADCs:Successive approximation and delta-sigma
  • Analog circuits: Bandgap references, LDOs, operational amplifiers, oscillators, current sources, switched capacitor circuits, low voltage/low power techniques, high voltage signal isolation
  • Mixed signal: Interface between digital and analog blocks and mixed mode simulation

During his time at Texas Instruments he was promoted to be a member of technical staff for his contribution, deep knowledge, and experience. He currently holds seven patents in electronic circuit design.


Dipl.-Ing. Hans-Georg Schinner

: Design, verification and synthesis of digital circuits, low power design methodology, microcontroller

Experience: After his graduation from Friedrich-Alexander- University Erlangen-Nuremberg in 1995, Mr. Schinner worked at the Fraunhofer Institute for Integrated Circuits IIS-A on different customer projects and in IP development. 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.


IC-Production Test

Dr.-Ing. Martin Allinger

Competencies: IC production test in the fields of power management and high-precision-analog; test platforms: Verigy 93k, LTX-Credence X-Series, Teradyne Catalyst, Eagle

Experience: Martin Allinger studied Electrical Engineering with focus on microelectronics at the Friedrich-Alexander University Erlangen-Nuremberg. He started his career in 2007 at Texas Instruments as a Development Engineer with focus on production test solutions for high-resolution data converters. In 2012, he acquired his doctorate degree at the Friedrich-Alexander University Erlangen-Nuremberg and joined the eesy-ic development team in Nuremberg.
