Current Activity
After working at
Texas
Instruments Deutschland GmbH for 3½ years
and at Infineon Technologies AG for 4½ years,
I am now with Rohde & Schwarz GmbH & Co. KG
in Munich, Germany,
where I am designing high-speed analog integrated circuits for use in measurement equipment.
The Six-Port Reflectometer
The subject of my PhD thesis was a device called
six-port reflectometer.
I did this work in the
microwave group
of the Département
Communications et Électronique at the
École Nationale Supérieure des
Télécommunications, Paris, France.
You can download
some basic articles
about the operation of the six-port reflectometer,
my own articles
in which I summarize the results of my research,
and also my entire PhD thesis
(available in French only).
The implementation of the
calibration method
I have developed is also available.
Loop Gain Simulation
I have implemented two recently developed methods for accurate
loop gain simulation.
The implementations are for the free
LTspice
simulation program but can be adapted for other SPICE simulators as well.
Gottlieb Daimler- und Karl Benz-Stiftung
My PhD thesis was made possible by a research grant from the
Gottlieb
Daimler- und Karl Benz-Stiftung.
They have a
scholarship
program for young Germans pursuing a PhD thesis
in foreign countries as well as for foreign PhD students
undertaking research in German institutions.
The program is open to all disciplines, subjects, and countries.
The information about this program is also available
in
German.
