My research activity started in January 1991 when I got a pre-doctoral scholarship from the Ministry of Education and Science, and started my doctoral thesis at the Polytechnic University of Catalonia in the field of testing of digital integrated circuits.

Since then, I have been working on basically three research topics:

a) Test and verification of ICs. In the first research stage, I worked on the detection of faults in microelectronic circuits, primarily through observation of the current consumption, both static (IDDQ) and dynamic (IDDT). Studies were extended to not only digital circuits but also analog sections and even radio frequency circuits. The work done ranges from fault modelling to sensor design and conducting experimental measurements. Given the evolution of microelectronic technologies, they happen to have important variations in technological parameters, which leads us to extend studies to test techniques that consider the variability of parameters of the circuits. That makes us start research on predictive test, oscillation-based test, auto-tuning techniques, topics which represent a major challenge within the community of integrated circuit test. Within this area of work, I have co-authored 15 articles in international journals with impact index (SCI).

b) Design of sensors to detect the total dose of ionizing radiation (TID) made standard MOS integrated circuits. The first generation of sensors detected when the TID exceeds a critical value. Currently we are focusing on producing an output current or a digital output whose frequency is proportional to the TID, and are based on floating gate MOS transistors. On this subject, I have co-authored 5 articles in IEEE Transactions on Nuclear Science.

c) In the last 7 years, I have been working in the development of new non-conventional computing methodologies accelerated in hardware to allow the application of artificial intelligence systems to massive and highly complex problems. On this subject, I have co-authored 3 articles in international journals with high impact index (SCI)
