摘要

本文提出了一种用于在线(实时)校正任何模数转换器(ADC)中积分非线性(INL)的数字校准技术。MATLAB仿真验证了该技术在初始无杂散动态范围为80 dBFS的12位ADC上实现了约20 dB的改进。作为奖励，这种技术还可以纠正偏移误差。为这些好处所付出的代价是包含一个相同的额外ADC和一些额外的DSP电路。

On-line digital correction of the harmonic distortion in analog-to-digital converters

A digital calibration technique for the on-line (real-time) correction of the Integral Nonlinearity (INL) in any Analog-to-Digital Converter (ADC) has been presented in this paper. MATLAB simulations substantiating the technique achieved around 20 dB improvement on a modeled 12-bit ADC with an initial Spurious-Free Dynamic Range of 80 dBFS. As a bonus, this technique can also correct for the offset error. The price paid for these benefits is the inclusion of an identical extra ADC, and some additional DSP circuitry.
