Linearization of ADCs via digital post processing

Volterra series offers a practical tool for mathematical modeling of nonlinear systems such as Analog to Digital Converters (ADCs). In this paper, we report of ADC linearization by employing Volterra model and digital post processing. We first obtain the Volterra model from calibration data by using a Vandermonde matrix. Then, we employ an efficient method for data collection, which are employed to build an ADC module. The model is then used to estimate and compensate the nonlinearity.
