Nicolas Constantin

Nicolas Constantin is a Professor in the Department of Electrical Engineering at École de technologie supérieure (ÉTS), Université du Québec, where he teaches courses including Electrical Circuits (ELE105) and Analog Microelectronics (SYS811). His research focuses on analog and RF microelectronics, microwave circuits, and wireless communications, with specific expertise in RF transmitters and receivers, test methods for analog and RF circuits, and power integrity in high-speed switching systems.

His educational background includes:

• B.Eng. from École de technologie supérieure (ÉTS)
• M.Sc.A. from Polytechnique Montréal
• Ph.D. from McGill University

Dr. Constantin's research spans multiple domains within electrical engineering, with a consistent focus on improving the linearity and efficiency of RF power amplifiers through innovative techniques like positive envelope feedback. His work bridges fundamental circuit design with practical applications in wireless communications, aerospace systems, and power electronics. Recent research has expanded into GHz-range power integrity modeling for switch-mode converters, millimeter-wave identification systems, and integrated solutions for avionic applications, demonstrating both depth and evolution in his technical contributions.

Analyzing his publication record from 1995 to 2025 reveals a clear progression from fundamental device characterization to sophisticated integrated system solutions. Early work focused on GaAs FET behavior and nonlinear analysis of power amplifiers, while more recent publications address system-level challenges in power integrity, millimeter-wave identification, and aerospace electronics. A consistent thread throughout his career has been the development of envelope feedback techniques for RF power amplifiers, which has resulted in multiple patents and continues to drive innovation in wireless communication systems.

Dr. Constantin has actively supervised numerous graduate students through doctoral and Master's research projects. His students have explored topics including positive envelope feedback techniques, power integrity in SiP implementations, millimeter-wave antenna systems, and integrated control circuits for aerospace applications. His supervision spans both theoretical analysis and practical implementation, preparing students for careers in both industry and academia.

As a key member of the LACIME (Communications and Microelectronic Integration Laboratory) at ÉTS, Dr. Constantin contributes to a research environment that spans from functional materials to communication protocols. The laboratory's multidisciplinary approach enables innovative solutions in micro- and nanofabrication, integrated circuit design, and photonic systems, with strong industry partnerships that facilitate technology transfer and real-world application of research findings.
