摘要

我们提出了一种混合模数转换器(ADC)，将第一级作为一阶前馈增量(FF I-) ADC，第二级作为SAR(逐次逼近寄存器)ADC作为高精度和高速ADC。仿真结果表明，在一阶I-ADC FF路径电容存在10%误差的情况下，该混合ADC仍能正确转换数据。

Investigation of Hybrid ADC Combined with First-order Feedforward Incremental and SAR ADCs

We propose a hybrid Analog to Digital Converter (ADC) combined with the first-stage as a first-order feedforward incremental (FF I-) ADC and the second-stage as a SAR (Successive Approximation Register) ADC as high-precision and high-speed ADCs. As a result of simulation, the proposed hybrid ADC correctly converts data even if capacitance in FF path of the first-order I-ADC has 10% error.
