Research at the Integrated Circuits Laboratory encompasses modeling, characterization and design of RF, analog and digital integrated circuits with a strong emphasis on transistor level CMOS design. Our group was a pioneer in the development of switched-capacitor and continuous-time circuits fully compatible with digital technology, and charge-based compact MOSFET models.
Current research in analog circuits focuses on modular, programmable circuits for ultra-low-voltage and low-power applications, including energy harvesting, power management, integrated sensors and implantable devices.
News: (June 28, 2023)A proud moment for our Integrated Circuits Laboratory. We are excited to receive the best paper award at the 21st IEEE Interregional NEWCAS 2023 Conference for our paper entitled "A 5-DC-Parameter MOSFET Model for Circuit Simulation in QucsStudio and Spectre". The paper presents a minimalist MOSFET model for circuit simulation with only five DC parameters written in Verilog-A. The simulation of some basic circuits using the proposed 5-DC-parameter MOSFET model matches the simulation using the BSIM/UTSOI models for the benefit of a much more straightforward set of DC parameters. THE ACM-5PM can be used in open-source or commercial circuit simulators due to the universality of the Verilog-A language. Kudos to Deni Germano Alves Neto, Cristina Missel Adornes, Gabriel Maranhão, Mohamed Khalil Bouchoucha, Manuel J. Barragan, Andreia Cathelin, Márcio Cherem Schneider, Sylvain Bourdel and Carlos Galup-Montoro for this great work and collaboration. NewCAS Presentation  (Oct 27, 2021) The paper "Bridging the gap between design and simulation of low voltage CMOS circuits" was presented at IEEE Nordic Circuits and Systems Conference (NorCAS 2021) by Cristina Missel Adornes, one of the coauthors and who recently received the Master's degre in the same subject of the paper. The paper is also coauthored by Deni Germano Alves Neto, graduate student of the Integrated Circuits Laboratory, and professors M rcio Cherem Schneider and Carlos Galup-Montoro.
