ACCURATE PREDICTION OF ANALOG-TO-DIGITAL CONVERTER

Henrik Lundin, Peter Händel, Mikael Skoglund

Abstract

Analog-to-digital converter additive postcorrection using look-up-tables is considered. An accurate expression is provided that predicts the ADC performance after correction. The expression depends on differential nonlinearity, random noise variance, and the numerical precision of the correction terms. The theory shows good agreement when compared with simulations and experimental converter data.
