Institute for Electronics Engineering

The Institute for Electronics Engineering (www.lte.tf.fau.eu) is engaged with design of microelectronic, monolithically or hybrid integrated circuits, components and systems for both wireless and wired communication and sensing. Our research encompasses both the design and experimental characterization in the frequency range from DC to 400 GHz and the development of signal processing and deep learning algorithms.

The research work is embedded into cooperation projects funded by the EU and German and Bavarian ministries and research associations as well as directly funded by DFG or industry. All of our research is hardware-oriented. We are researching in the fields of mobile communication hand-sets and base stations, radar, local positioning, scanning and tracking systems, various sensor technologies, integrated RF/mixed.signal circuits, electronic hetero-integration and packaging for industrial, scientific and medical applications.

    Passive radar technology represents a promising addition to conventionalradar systems. With increasing demands from economy and politics to completelyuse the limited spectrum of the frequency bands limited for telecommunicationsand location, the interest in this technology is increasing.

    The aim of this research project is to establish the technology of locationusing passive radar technology in civil air traffic control in Germany and to opennew areas of application.

    To improve the detection performance, various options for setting up afrequency-selective analog receiver for the FM band are being developed andintegrated into an existing passive radar system. For the highest possiblesensitivity, filtering in different stages of the receiver is essential.However, this must be evaluated together with the frequency-converting stagesin the overall system context in order not to degrade the signal quality,including through possible imperfections in the analog implementation. Furthermore,attention must also be paid to an optimal balance between circuit complexity,costs and compactness of the receiver. For this purpose, the receiverarchitectures are first examined in system simulations and evaluated regardingthe requirements from the application. This is followed by a prototypeconstruction of the most promising concepts with metrological verification ofthe individual components and evaluation of the entire system in a field test.

    Alternating-Contactthin-film transistors (ACTFTs) provide new degrees of freedom for deviceoptimization and deployment. This project specifically aims at providingcost-effective implementation of flexible RF circuits through the use of shortchannel ACTFTs with self-aligned contacts. With the Chair of Electron Devicesand the Institute of Electronics Engineering of the FAU Erlangen-Nuremberg, tworenowned institutes of semiconductor electronics and RF circuit technology workhand in hand on the integrated development of RF circuits and systems. Based onmetal oxide ACTFTs, key components of receivers and transmitters (e.g. lownoise amplifiers, oscillators, or mixers) are implemented on flexiblesubstrates. New perspectives for thin, flexible applications in industrial,consumer and textile / wearable electronics are presented.
