This paper presents the development of a mixed-signal multi-functional system for current measurement and electrical stress detection. The system is composed of a tracking ADC and a double range (a coarse and a fine one) current-steering DAC. The coarse range, designed for the full-scale input values [0A:108A], has a 5b resolution and it is used for the stress detection feature. The fine range is for lower input current values [4A:14A] and it is used for the current measurement, where more accuracy is required. With respect to the full-scale, the resolution of the fine range is 8b.

Abstract
This paper presents the development of a mixed-signal multi-functional system for current measurement and electrical stress detection. The system is composed of a tracking ADC and a double range (a coarse and a fine one) current-steering DAC. The coarse range, designed for the full-scale input values [0A:108A], has a 5b resolution and it is used for the stress detection feature. The fine range is for lower input current values [4A:14A] and it is used for the current measurement, where more accuracy is required. With respect to the full-scale, the resolution of the fine range is 8b.
