Digital calibration techniques for interstage gain nonlinearity in pipelined ADCs

摘要

Main digital calibration techniques for interstage gain nonlinearity in low-power, high-speed pipelined analog to digital converter (ADC) designs published in recent years are overviewed in this paper. Two novel digital calibration techniques are proposed and compared with other main digital calibration techniques in terms of the efficiency, convergence time, complexity, limitations, and cost.
