M.Sc. Patrick Vogelmann

I studied electrical engineering at the University of Ulm and received my B.Sc. degree in 2013 and my M.Sc. degree in 2015. My Master thesis dealt with the "Design and Implementation of a Multiplexed Sample-and-Hold Amplifier for a 16-Bit Incremental Σ∆-Modulator in 180nm CMOS".

Since November 2015 I am working towards the Ph.D. degree under supervision of Professor Dr.-Ing. Maurits Ortmanns. My research activities focus on the design of high-resolution incremental Σ∆-Converters.

High-Resolution Incremental Sigma Delta ADCs for Biomedical Signals

P. Vogelmann:  In the past few years, an increased interest in biomedical implants like neural recorders is noticeable as measured by the number of publications. These devices are integrated circuits (ICs) that comprise more and more functionality which increases their versatility and importance in medical research...  [more]

CMOS Circuits for Multi-Channel, Bidirectional Neural Interfaces

S. Reich, M. Sporer, M. Haas, M. Pagin, P. Vogelmann: Bidirectional, neural interfaces are a tool which is widely used in the study of the complex interconnections between neurons within the brain. To understand the activity of neural cells, nervous tissue is first stimulated with a current or voltage signal and afterwards its electrical activity is observed ... [more]
