M.Sc. Michael Pietzko

I studied electrical engineering at Saarland University, where I received my B.Sc. degree in October 2016. I continued my studies at the University of Ulm, where I received my M.Sc. degree in January 2020. From October 2018 to March 2019, I worked as an intern in the ASIC Design group at the Robert Bosch Research and Technology Center (Sunnyvale, CA). The topic of my Master thesis was ''Highly Linear Gm-C based Sigma Delta Modulator''.

In February 2020 I started working towards my Ph.D. degree at the Institute of Microelectronics at the University of Ulm under the supervision of Prof. Dr.-Ing. Maurits Ortmanns. My current research interest is in the field of ultra-low power continuous-time Sigma-Delta analog-to-digital converters.

Ultra-low Power, Wide Bandwidth Continuous-time Sigma Delta Analog to Digital Converter Design

A. Abdelaal, M. Pietzko: Continues time delta sigma modulators (CTDS) have recently become the key device for broadband wireless and wireline communication.  Due to there built in anti-aliasing filter and the ability to have relaxed sampling requirements the CTDS modulators are preferred over there discrete time counterparts ...
