Abstract
An example method includes extracting calibration coefficients of each stage of a pipeline analog-to-digital convertor (ADC). The calculation of the corrected digital output of the pipeline ADC can be based on the digital output of each pipeline stage and the estimated calibration coefficient of the corresponding stage. Therefore, a relaxed design of the operational amplifier and sizing of capacitors in a high speed asynchronous ADC can be achieved.
