“…An interesting high-speed sensing technique is presented in [6], while the authors of [7] present a very simple current sensor for on-chip current monitoring circuit which produces an analog output proportional to the quiescent current. By contrast a general-purpose sensor interface is presented in [8] where more complicated functionalities like self-calibration, self-validation and built-in-self-test are described.…”

A built-in configuration for monitoring the good operating condition of an instrumentation system (with analog and digital circuits) in real-time, is presented in this work. The approach is based on a current monitoring circuit which records the changes in the power supply current of the system without practically interfering the operation of the system and sums it within a specific time period. The comparison of the resulting power consumption measurement for hardware modules while executing certain tasks (defined in time by the software) with already known values may indicate the good operating condition of the system. This methodology may also provide information useful to power optimization techniques.

A microcontroller-based gas sensing system is presented in this paper. The poor selectivity of SnOl sensors is improved by the consideration of temperature variation. The analysis presented here exploits the differences in the steady-state performance of SnOl gas sensors and the potential use of such differences yor improving their selectivity and sensitivity. Sets of experimental measurements of sensitivity versus temperature are used f o r the detailed presentation of this technique. The results shown here'indicate that selective identification and accurate measurement of a mixture of CH, and CO gases is quite possible by this method. Finally, a microcontroller-based configuration is presented as . a working example of a small size implementation, which may offer measurements of improved sensitivity and selectivity along with high accuracy and reliability.
