So digitalizing analog signal is the trend of information technology, in which Analog to Digital converter plays an important role.

所以模拟信号数字化是信息技术的发展趋势，而模数转换器在其中扮演着重要的角色。

However, in the real world, the performance of an analog to digital converter is constrained by many factors.

但是，在真实世界中，模数转换器的性能受到许多因素制约。

Analog to Digital Converter is the interface of analog and digital circuit, its use is very extensive.

模数转换器是模拟电路和数字电路的接口，其用途非常广泛。

One of these constraining factors is self generated noise within the analog to digital converter.

这些制约因素之一是在模数转换器内自生的噪声。

Low power, low cost and noise free is a hot research on the field of analog-to-digital converter.

如何使模数转换器既拥有较强的抗干扰能力，同时达到低功耗的要求，越来越成为模拟集成电路研究的热点和难点。

However, it is a tradeoff project to develop digitized receivers because of the limitations of analog-to-digital converter , digital signal processing , etc.

但由于受到模数转换器和数字信号处理等技术发展水平的限制，研究数字接收机成了一种折衷的方案。

The output of the sample-and-hold system now goes into an analog-to-digital converter.

取样和保持系统的输出现在又进入一个模数转换器。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
