Josep Altet Sanahujes

Josep Altet Sanahujes is an Associate Professor in the Department of Electronic Engineering at the Polytechnic University of Catalonia (UPC). His research focuses on high-performance integrated circuits, particularly leveraging thermal measurements to characterize and optimize RF analog circuits. He leads the HIPICS (High Performance Integrated Circuits and Systems Design) group, specializing in temperature sensor development for on-chip testing and monitoring of aging effects in CMOS amplifiers.

Education:

• M.S. in Electronic Engineering, La Salle Universitat Ramon Llull (1993)
• Ph.D., Electronic Engineering Department, Universitat Politècnica de Catalunya (1998)

Research Interests: Dr. Altet pioneers thermal-based strategies for analog circuit testing, including the design of compact temperature sensors compatible with RF technologies. He explores thermal coupling characterization and electro-thermal interaction in integrated circuits, with applications in automotive AI, energy-efficient DNN accelerators, and astrophysical instrumentation. His work bridges fundamental physics (e.g., thermal phase lag analysis) with practical device optimization.

Key Contributions: His recent articles address cutting-edge topics like energy-efficient mixed-precision DNN inference via binary segmentation, aging compensation in RF amplifiers using DC temperature measurements, and security enhancements through thermal signatures. He has published extensively on topics ranging from heterodyne infrared imaging for current tracking to BPF-based thermal sensors.

Lab & Teams: Primary affiliation with the HIPICS research group at UPC, collaborating on interdisciplinary projects involving thermal-aware circuit design and embedded systems.
