Professional 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.

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.

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.

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 had 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 was open to all disciplines, subjects, and countries. Unfortunately, this program has now been terminated and has been replaced by a program for young postdoctoral scientists in Germany
