Using Bulk Built-in Current Sensors to Detect Soft Errors

Calibrating Bulk Built-in Current Sensors for Detecting Transient Faults

This work presents a novel circuit for detecting transient faults in combinational and sequential logic. The detection mechanism features a built-in current sensor connected to the bulks of the monitored logic. The proposed circuit was optimized in terms of power consumption and enhanced with low-power sleep-mode. In addition, a calibration method for bulk built-in current sensors is presented....

Bulk built in current sensors for single event transient detection in deep-submicron technologies

As device dimensions are scaled down, single event transients (SET) are increasingly affecting the reliability of integrated circuits. An SET is a transient voltage perturbation caused by an energetic particle strike at the semiconductor. This work studies the applicability of bulk built in current sensors (bulk-BICS) for SET detection in deep-submicron technologies. The bulk-BICS detects the t...

Using Networked Sensors to Detect Ambient Light

An understanding of the capabilities of the Mica mote light sensors is currently limited. To determine how much information data from the light sensors reveals about the environment, we performed a series of experiments designed to test the sensitivity of the light sensors to the time of day, the presence/absence of close objects, and different colors. Measuring the ambient light alone, we disc...

Synthesis of Iddq-testable Circuits: Integrating Built-in Current Sensors

"On-Chip" IDDQ testing by the incorporation of BuiltIn Current (BIC) sensors has some advantages over "offchip" techniques. However, the integration of sensors poses analog design problems which are hard to be solved by a digital designer. The automatic incorporation of the sensors using parameterized BIC cells could be a promising alternative. The work reported here identifies partitioning cri...
