Circuit design

CAS

The CAS (Circuits and Systems) team carries out high-level research activities in the fields of radio frequency (RF), analogue and mixed-signal integrated circuit design. It combines strong expertise in frequency synthesis, architecture and radiation hardening to focus its research on three application areas: wireless communications, space and aeronautics, and bio-electronics. These orientations are structured by 3 innovative design methodologies that involve all competencies: Design by Mathematics (DbM), Design for Availability (DfA) and Design for Human (DfH).

Circuits and Systems Team

We design integrated circuits for applications

“Circuits and Systems” Team (CAS) has research activities in RFIC design. Dr. François RIVET is the head of the team. It is composed of 3 faculties, 8 Ph.D. students, 2 engineers, and 3 master students. CAS Team is an application-oriented research team:

CAS Team develops its own methodologies for IC design

CAS Team uses various technologies (65nm CMOS STM, 28nm FDSOI STM, 65nm CMOS TSMC, 0.18um UMC) to design its different building blocks, circuits, and systems (PLL, DLL, VCO, SASP, RF-ADC, Walsh Tx, Riemann Pump, OPA, LDO, TIA, BandGap, BIST, BISC).

Résumé en français

L’équipe CAS mène des activités de recherche de haut niveau dans les domaines de la conception de circuits intégrés Radiofréquences (RF), analogiques et mixtes. Elle combine des expertises fortes en synthèse de fréquence, en architecture et en durcissement aux radiations pour orienter sa recherche dans 3 domaines applicatifs : les communications sans fil, l’espace et l’aéronautique et la bio-électronique. Ces orientations sont structurées par 3 méthodologies de conception innovantes qui font intervenir toutes les compétences: la conception par les mathématiques (Design by Mathematics, DbM), la conception pour la fiabilité étendue (Design for Availability, DfA) et la conception pour le corps humain (Design for Human, DfH). Avec des relations partenariales toujours aussi fortes et diversifiées, l’équipe CAS continue sa recherche sur la conception du circuit au système en analysant les compromis et les opportunités offertes par les nouvelles technologies (FDSOI, sub 20nm) notamment pour la réduction de la consommation et la montée aux fréquences sub-THz, la robustesse des circuits à des environnements contraints (spatial et nucléaire) et des architectures de rupture pour les futurs standards de communication comme la 6ème Génération de téléphonie mobile (6G).
