Adaptive Filtering For ADC Spectral Analysis

• Abstract:

  In this paper, we present an adaptive filter structure for Analog to Digital Converters (ADC) spectral domain analysis. A digital filter bank is commonly used to decompose an ADC output signal into its main spectral components. However, this method requires a priori accurate knowledge of the output characteristics. It implies that a slightly deviation from the calculated resonant frequency results in a drastic decrease in the parameters estimation precision. In order to solve this problem, we propose a promising adaptive structure for a Built-In-Self-Test (BIST) approach for ADC and Mixed-Signal Integrated Circuits (IC).
