The research activity is focused on the design, modelling, advanced characterisation and integration of microsensors and microelectronic circuits. In this sense, and in close collaboration with other groups in our immediate environment, at national and international level, we have developed capabilities in the design of sensors based on nanostructured layers for the sensing of physical magnitudes such as the magnetic field or the concentration of gases. We have also demonstrated skills in the design of polarisation circuits for these sensors, signal conditioning and data acquisition.

• Diseño, modelado, caracterizacion avanzada e integracion de microsensores basados en capas nanoestructuradas para medida de campo magnetico y deteccion de gases. Diseño de circuitos microelectronicos avanzados de polarizacion, acondicionamiento y adquisicion para estos sensores. Integracion de ambos mediante tecnologias CMOS estandar

• Design of magnetic microsensors.Development of solid-state magnetic sensors based on the giant magnetoresistance (GMR) effect. Design of optimal application-oriented structures. Complete definition of the manufacturing process. Comprehensive analysis including finite element modelling (FEM) and electrical and functional characterisation: sensitivity, thermal drifts, noise level, frequency response, etc. Proposal, development and evaluation of applications: electrical current measurement, gradiometers.
• Analogue microelectronics for sensor biasing, acquisition and conditioning signal.Microelectronic design of polarisation, conditioning and acquisition circuits for the sensors described. For polarisation we study advanced current sources, oscillators, multiplexed excitations... We work with advanced amplifiers with specific characteristics (lock-in, low noise...).
