Abstract :
Oscillation-based test (OBT) techniques show promise in detecting faults in mixed-signal circuits and require little modification. to the circuit under test. Comparing both the oscillation´s amplitude and frequency yields acceptable test quality. OBT seems especially appealing for filters but requires adaptation to handle monolithic circuits or the analog-core-based design of complex mixed-signal ICs.
