Forschungsschwerpunkte
Der Einsatzbereich reicht von High-Speed-GS / s integrierte Schaltungen (IC) für Wireless-Infrastruktur-Anwendungen (wie LTE-Basisstationen), über energieeffiziente DSP-basierte Transceiver für optische Anwendungen (wie beispielsweise Silicon Photonics) bis zu ultra- Low-Power-Auslesesystemen für optische und biomedizinische Sensoren als auch zum Design von ultra-robusten Automobil integrierten Schaltungen. Energieeffiziente (RF) -Transceiver-Architekturen, Energy Harvesting Ansätze für mobile / Handheld-Geräte und der große Bereich der Internet-der-Dinge (IoT) Technologien sind weitere wichtige Forschungsthemen.
- Datenumwandlungstechniken mit Schwerpunkt auf Robustheit, Energieeffizienz sowie Siliziumbereich / Kostenreduktion
- Low-Power-Breitband wireline- & Wireless-Transceiver, geräuscharme Sensorauslesung
- Mixed-Signal-Fehler- und Fehlanpassung Schätzalgorithmen, (Selbst-) -Adaptive Kalibrierungstechniken und hoch skalierbare DSP-basierte Design-Techniken
- Halbleiter-Design-Flow, Entwurfsautomatisierung sowie CAD-Tool-Entwicklung bis zu 14nm FinFET-Technologien.
