本文提出了一种适用于模拟电流模式处理的有效失配补偿方法。在当前和未来的混合模式处理系统中需要这样的方法，该混合模式处理系统除了利用传统的数字逻辑之外还利用模拟处理。所提出的设计利用了可随制造工艺缩小的模拟处理器件，因此以更小的实现面积的形式利用了CMOS技术的优势。采用的输入电流范围是1微安到10微安。该示例性电路可以在0.15um的实现面积为65Mum2的情况下，在4sigma置信度区间内被校准在标称值的1%以内
In this paper, we present an effective mismatch compensation method for analog current mode processing. Such a method is required in current and future mixed-mode processing systems, which take advantage of analog processing in addition to conventional digital logic. The proposed design utilizes analog processing devices that can be scaled down with the manufacturing process, therefore employing the advantages of CMOS technology in the form of a smaller implementation area. The range of input currents employed is 1 muA to 10 muA. The example circuit can be calibrated within 1 % of the nominal value at the 4sigma confidence interval with 65 mum2 of implementation area in 0.15mum CMOS technology
