M.Sc. Matthias Häberle

I studied microsystem engineering at the University of Freiburg, where I received my B.Sc. degree in April 2012. I continuted my studies in electrical engineering at the University of Ulm and received my M.Sc. degree in April 2016.

The topic of my Master's Thesis was "Design and implementation of a CMOS transimpedance amplifier with low noise and high bandwidth for high-resolution spectroscopy- and microscopy applications.

In May 2016 I began my work at the University of Ulm towards the Ph.D. degree under the the supervision of Professor Dr. Jens Anders. My research area is analog CMOS circuit design, with a focus on transimpedance amplifiers for scanning ion-conductance microscopy and electrically detected magnet resonance applications.

Transimpedance Amplifiers for Life and Material Science

M. Häberle: Many life and material science applications like Scanning Ion Conductance Microscopy (SICM) and Electrically Detected Magnetic Resonance put demanding constraints on readout electronics. In a SICM experiment a pipette is used to map the surface of soft biological samples. An EDMR experiment is used to derive the efficency of solar cell materials ... [more]
