Abstract :
This paper presents a theoretical analysis of the statistical requirements of a background correlation-based technique for calibration of pipeline ADCs. The calibration algorithm estimates adaptively the appropriate additive error codes which compensate both the gain and non-linear errors in the stage under calibration (SUC). Close equations for the transient evolution towards the stationary situation are obtained. Expressions for the effective number of bits (ENOB) and signal-to-noise ratio (SNR) at any updating step are also derived
