Eric Klumperink, the 6G-REFERENCE Technical Manager and Associate Professor at the University of Twente, delivered a presentation as an invited speaker titled “Highly Linear Time-variant Mixers/Filters: Operation and Analysis”, as part of a workshop organized by IMS and RFIC Technical Program Committee at the 2025 IEEE Microwave Theory and Technology Society (MTT-S) International Microwave Symposium (IMS2025), celebrated from the 15th to the 20th of June 2025 in San Francisco, United States.
The workshop in which Professor Klumperink contributed, attended by 30 participants and held on the first day of the symposium, was titled “Designing with time: Linear Periodically Time-Varying (LPTV) Circuit Approaches Enabling Advanced RFIC Applications”. In his presentation, he explained several time-variant techniques which are explored in the 6G-REFERENCE research, namely N-path filters/mixers, Time Modulated Arrays and FIR Filtering exploiting Filtering by Aliasing.
“Time-variant circuit design techniques bring new degrees of freedom to enhance wireless transceiver spatial and frequency selectivity and linearity.” – Eric Klumperink
