%X Calibration is a crucial technique for the implementation of high-speed and high resolution analog-to-digital converters.This paper describes the structure of a pipelined ADC,analyzes the sources of errors in the pipelined ADC,focuses on a calibration algorithm that gains the weights by calculating the height of the jumping point of the transition function,presents its implementation scheme,and gives the implementation results and layout of the calibration system.Implementation the calibration system is simple and requires only pure digital circuits.Meanwhile,the simulation of this algorithm shows that it meets the requirements of high-resolution ADCs,and,with respect to availability and reliability,it is a well implemented scheme.
