Etude et conception d’une structure BIST pour convertisseur analogique-numérique

Abstract : Analog and mixed circuit testing is more and more difficult because of the integration of agrowing number of complex components in one system. BIST techniques allow the realizationof an effective test system by integrating the test resources to the system. In this thesis, wepresent a BIST Structure for Analog to Digital Converters (ADC). The stimuli generatoris a digital Sigma-Delta oscillator delivering a sine wave after a simple analog filtering. Abank of digital filters separating the different harmonic components of the signal from theADC is used to analyze of the response. From these harmonic components, different spectralparameters are calculated. To validate this structure, different prototypes have been designedon FPGA. The experimental results confirm the ability of our structure to effectively test a12-bit ADC with a 70-dB-SNR.
