本文首先回顾了实现高速模数变换的各种方法,提出用多个模数变换器构成流水线式结构的模数变换模块,可以实现超高速采样率,并指出总误差仍同单个器件相当,因此这是获得超商速采样率的一种很有效的方法。
In this paper, we first review various methods to achieve high-speed A / D conversion. We propose a modular analog-to-digital conversion module with a plurality of A / D converters to achieve a very high sampling rate and indicate that the total error is still comparable to a single device. This is a very effective way to get super-fast sample rate.
