About the Mixed-signal Microelectronics group
The research area of the group is advanced purely-analog and mixed-signal IC design (RF/IF/LF), applied to frontends, especially for wireless RF transceivers and sensors. In this context, frontends are defined as the functional blocks that process and translate analog signals (communication signals, sensor signals) to digital signals (bits), and vice versa, see the figure below. This includes on the one hand system, concept and algorithm level design, and on the other hand circuit block design (antenna-matched low-noise amplifiers, sensor amplifiers, power amplifiers; oscillators, mixers, modulators, detectors; data converters). At all these levels, we strive to implement smartness (autonomous calibration, adaptivity, error correction, reconfiguration, etc.).
As regards performance, we focus on improvements in speed (up to THz), power-efficiency, and ultra-low-power. As regards the application domains, our current focus is on communication systems, sensor systems, and medical systems. As regards technology, we focus on advanced deep-submicron processing (CMOS, BICMOS), emerging technologies (organic electronics, metal oxides), and THz technology.
Our mission is:
- to educate students to become top-level academic people, who feel responsible for our society and can address challenges in terms of societal, scientific, and industrial needs;
- to contribute to science by high-level fundamental research;
- to apply our fundamental knowledge to advanced system and circuit design in very close cooperation with industry, aiming for optimal synergy, efficiency, and effective dissemination, thus contributing to the innovation chain.
