Abstract
In this paper the theoretical analysis of Low-frequency (LF) noise sources in Optoelectronic Coupled Devices (OCDs) is given and the relation between typical defects and LF noise (1/f noise, generationrecombination (g-r) nosie and burst noise) is described. According to LF noise sources of OCDs and device reliability estimation methods, a novel measurement system based on virtual instrument for OCDs is introduced and nV-level measurement precision can be achieved with the typical LF noise measurement system, which can be used to screen potential devices with excess noise and assess device relibility classifications. In this experiment, the top and bottom limitative thresholds were used to estimate the components parameters of the Power Spectrum Density (PSD) for estimating the reliability of OCDs by the average noise PSD for the 200 OCDs and the classification criterions of electronic components. The experimental results demonstrated that high reliability requirements can be satisfied.
