J FrancaJosé Epifânio Franca is head of a research group at the Instituto Superior Técnico in Lisbon, working on circuit techniques, methodologies and computer-assisted design tools for mixed analogue-digital integrated circuits. Some of this activity is beig carried-out in the framework of the European Community Esprit Programme and in cooperation with various European companies. He has published on switched-capacitor circuits and systems, especially for multirate signal processing, data convertors, where he holds one USA patent for a mixed analogue-digital building block combining data conversion and filtering, and high-level automated synthesis tools. He is co-author with M. Ismail of 'Introduction to analog VLSI design automation'. He is a member the Editorial Board of Analog Integrated Circuits and Signal Processing, and a Senior Member of the IEEE. Read More Read Less
