Description
Summary:This paper presents current-mode electronic cells designed for sensor analogue interfacing and conditioning in embedded systems. A digitally programmable element allows modifying the circuit operation, tuning the system behaviour according to changes in the sensor operation and reducing undesired effects as device mismatching. Circuits have been designed to give a good signal transfer, upholding their functions, and reducing load effects due to interconnecting them to build a conditioning architecture. Finally, a study of perturbative learning strategies for mixed mode tunable circuits is presented.
