Volterra Filtering for ADC Error Correction

Abstract

Dynamic non-linearity of analog-to-digital converters (ADC)contributes significantly to the distortion of digitized signals. Thispaper introduces a new effective method for compensation such adistortion based on application of Volterra filtering. Considering ana-priori error model of ADC allows finding an efficient inverseVolterra model for error correction. Efficiency of proposed method isdemonstrated on experimental results.
