German
After my A-level ("Neideck-Gymnasium Arnstadt"), which I have passed with mark “1.5”, and the civil service,
I had entered the Technical University of
Ilmenau in 1995. The course which I have chosen was electrical engineering.
During
my study I became very interested in two fields: microelectronic/sensors and
embedded controll (microcontrollers and DSPs). So I was quite happy with my task,
I had to solve during my engineer training course in England (ERA-Technology).
I had to develop smart sensor interfaces, which means sensor signal conditioning,
digital calibration, calculation and data communication with PCs. The high-light
of my projects has been a Profibus-compatible high temperature contact less
thermometer. This thermometer is now used in measurement systems e.g. for
controlling blast furnace.
After Part1 of my study I
have chosen the specialization microelectronic/sensors. This meant a lot of
basic knowledge in semiconductor physics, technology.. etc. But still I was very
interested in information technology. That’s why I have taken part on nearly
every course, you need to pass this specialization as well. The thing was, that
I haven’t done this for collecting certificates, but for interest.
As my study-year-work I have done my first chip design. The power-devices-team is the most active chip design group on University. The current topic is the efficient controll of IGBTs. For such a controll-IC I have developed a high-speed comparator, which is used for symmetrying of parallel IGBTs.
Also for my master degree
I have chosen a chip design task. I have applied by the "Thesys
GmbH" (Erfurt, Germany),
which I had already contacted during my study-year-work, getting support from
them. Subject is the development of a USB-transceiver-cell, which will be used
in the new TH6503.4 - USB-bridge. At the first, this task has seemed to be easy,
but quickly I recognized, that this wasn’t the case. These cells are the
critical part of a USB chips. I have analyzed several circuit principles, but at
the end I found a completely new circuit, which is doing the job in low cost
technology.
Directly after the degree I did start the work for my PhD at the research and predevelopment department of the Robert Bosch GmbH (Stuttgart, Germany). The topic “Signal conditioning of smallest capacitive signals at aF-range” did result in a thesis with the title "Optimisation of the Development Method for Microelectromechanical Angular Rate Sensor Systems". I graduated my PhD with "Summa Cum Laude", which is a "very good with decoration".
