Thermal testing using oscillation based test structures
نویسنده
چکیده
Introduction: Oscillation based test (OBT) method [1] has been applied to testing different types of analogue circuits [2-5]. In this approach, the circuit is transformed into an oscillator during the test mode and the frequency of oscillation is measured and compared to the reference value obtained on a known-good circuit operating in the same conditions. Circuit modification for the purpose of OBT consists mainly of adding switches or jumpers to select the normal or the test operation mode and some additional hardware (i.e., discrete components or external networks ) to put the circuit into oscillation.

Look up Table Based Low Power Analog Circuit Testing
In this paper, a method of low power analog testing is proposed. In spite of having Oscillation Based Built in Self-Test methodology (OBIST), a look up table based (LUT) low power testing approach has been proposed to find out the faulty circuit and also to sort out the particular fault location in the circuit. In this paper an operational amplifier, which is the basic building block in the ana...

−− This paper addresses the problem of testing continuous-time nuclear-pulse shapers using Oscillation-Based Test (OBT). The proposal is to convert the whole systems into non-linear oscillators, avoiding the partition in low-order sections. The design of the oscillators is very simple because the nonlinear elements are mathematically modeled using the describing function approach, and the study...

The oscillation-test strategy is a low cost and robust test method for mixed-signal integrated circuits. Being a vectorless test method, it allows one to eliminate the analog test vector generator. Furthermore, as the oscillation frequency is considered to be digital, it can be precisely analyzed using pure digital circuitry and can be easily interfaced to test techniques dedicated to the digit...
