Recently proposed power-gating structures for intermediate power-off modes offer significant power saving benefits as they reduce the leakage power during short periods of inactivity. Even though they are very effective for reducing static power consumption, their reliable operation can be compromised by process variations and manufacturing defects. In this paper, we propose a signature analysis technique...
It was shown recently that signature analysis can be used for the test, diagnosis and repair of a robust multi-mode power-gating architecture. A drawback of this approach is that it requires a tester in a production-test environment, and potentially expensive manufacturing steps are necessary to repair defective power switches. We propose a built-in self-test (BIST) and built-in-self-repair (BISR)...
A Build-In Self-Test (BiST) circuit suitable for embedded RF Mixers in System-on-Chip applications is presented in this paper. This is a defect-oriented test scheme that dynamically sets the Mixer to operate in homodyne mode. The DC level generated at its output is used to control the oscillation frequency of a simple voltage controlled oscillator. Deviations of the oscillation frequency from the...
