Abstract

A fully-analytical approach to estimate the statistics of dynamic non-linearity parameters of pipeline analog-to-digital converters (ADCs) in the presence of circuit non-idealities including capacitance mismatches and non-ideal opamps is presented. These parameters include the spurious-free dynamic range (SFDR) and the signal to noise-and-distortion ratio (SNDR). The simple closed-form formulas for SFDR and SNDR presented here are useful for design automation of highly-linear pipeline ADCs in order to extract the required values for the circuit-level specifications of the sub-blocks of converters. Behavioral simulations are presented to show the accuracy of the proposed equations.
