高速模数转换技术及其发展

The Technology and Development of High-speed Analog-to-digital

高速模数转换器（ADC）的结构主要包括全并行结构、内插式结构、两步式结构、折叠式结构、时间交织结构等,当然还可以将其中的一种或多种结构结合起来像折叠内插式、并行流水线式等等,但不外乎都是从这几种最基本的转换器上发展起来的。ADC转换速度除了与其选用的结构有关,其采用的工艺对其速度也有很大的影响。

The structure of High-speed analog to digital converter （ADC） mainly includes full parallel structure, interpolation structure, two-step structure, folded structure, time-interleaved strueture and so on. Of course, one can also combine one or more structures like the folding interpolation , parallel pipelined and so on, but nothing more than a few develop from the most basic converter. The conversion rate of ADC not only relate the structure, but also its use of process have a great impact to the speed.
