我们提出了一种利用nolm的光I/O多周期传递函数用于超快低分辨率电a /D转换器（adc）的分辨率增强方案。该方案将8周期光传递函数与3个5位电ADC相结合，可提供一个有效位数为7.86位的8位ADC。我们研究了ADC的有效分辨率、由于低分辨率ADC的分辨率而导致的非线性误差和缺失码以及分辨率增强ADC的输出比特数。
We propose a resolution enhancement scheme using optical I/O multiperiod transfer functions of NOLMs for ultrafast low-resolution electrical A/D converters (ADCs). This scheme can provide an 8-bit ADC with the effective-number-of-bits of 7.86 bit by combining 8-period optical transfer functions and three 5-bit electrical ADCs. We investigate the performance of ADC about effective resolution, the nonlinear error and missing code due to the resolution of low-resolution ADCs and the number of output bits of the resolution-enhanced ADC.
