Volterra filtration technique for IADC error correction, based on an a-priori error model

Abstract

Dynamic nonlinear effects contribute significantly to analog-to-digital converters (ADC) distortion. Volterra filtering can present an effective method for modeling and compensation of these phenomena. Considering an a-priori error model of ADC allows one to find an efficient inverse Volterra model for error correction. Method effectiveness is demonstrated on experimental measurements.
