Input-dependent integral nonlinearity (INL) model is developed for pipeline ADC post-correction. The INL model consists of a static and dynamic part. The INL model is subtracted out of the ADC digital output for compensation. Static compensation is performed by adjacent sets of gains and offsets. Each set compensates an output code k range. The frequency content of the INL dynamic component is used to design a set of filters blocks that performs ADC compensation in the time domain. The compensation scheme is applied to measured data of two 12-bit ADCs of the same type (Analog Devices AD9430). Performance improvements in terms of spurious free dynamic range (SFDR), signal-to-noise and Distortion ratio (SINAD), intermodulation istortion (IMD) are obtained.
