M.Sc. Markus Sporer

Markus Sporer received the B.Sc. and M.Sc. degree in electrical engineering at the University of Ulm in 2015 and 2018, respectively. For his bachelor thesis and as a student research assistant he worked on signal conditioning electronics for ESR applications. In his master thesis he designed and implemented a DC-coupled neural recorder with direct analog-to-digital conversion.

From September 2016 to May 2017, he worked as IC design intern in the integrated circuits group at the Robert Bosch Research and Technology Center (Palo Alto, CA, USA). In January 2019, he joined the Institute of Microelectronics working towards his Ph.D. degree unter the supervision of Prof. Dr.-Ing. Maurits Ortmanns.

Projekte

CMOS Circuits for Multi-Channel, Bidirectional Neural Interfaces

S. Reich, M. Sporer: 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]
