After my A-level ("Neideck-Gymnasium Arnstadt"), which I have passed with
grade “1.5”, and the civil service,
I entered the Technical University of
Ilmenau in 1995. I chose electrical engineering.
During
University I became very interested in two fields: microelectronic/sensors and
embedded control (microcontrollers, DSPs, FPGAs). So I was quite happy with the
topic of my engineer internship 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 highlight
of my projects was a Profibus-compatible high temperature contact less
thermometer. This thermometer is now used in measurement systems blast furnace.
After Part
1 of my study I
specialized in microelectronics
and
sensors. This
included
a lot of
basic knowledge in semiconductor physics, technology.. etc. But
at the same time I
was
very
interested in information technology. That’s why I
took nearly
every course you need to pass this specialization
in addition.
I haven’t done this for collecting certificates, but
out of interest
and for fun.
As my study-year-work I have done my first ASIC. The power devices team was the most active ASIC design group on campus. The topic back in the days was the efficient control of IGBTs. For such a control IC I developed a high-speed comparator and designed a test ASIC to charakterisiere it.
Also for my master degree
covered ASIC design. I applied
for a internship position at the "Thesys
GmbH" (Erfurt, Germany). Subject was the development of a USB-transceiver-cell, which was used
in the back then new TH6503.4 - USB-bridge. At the first, this task
looked easy,
but quickly I had to recognize that this wasn’t the
case. This mixed signal cell
is a
critical part of a USB chips. I analyzed several circuit principles, but at
the end I found a completely new circuit topology, which
was able to get the job done in a low cost
technology.
Directly after the degree I started my PhD at the research department of the Robert Bosch GmbH (Stuttgart, Germany). The topic “Signal conditioning of smallest capacitive signals at aF-range” resulted in a thesis with the title "Optimisation of the Development Method for Microelectromechanical Angular Rate Sensor Systems". I received the PhD with "Summa Cum Laude", which is a "very good with decoration".
