所以输出其实是一个阶梯曲线。 再结合前面说的环境噪声、也称作热噪声(thermal),那么一个ADC的总噪声就是热噪声和量化噪声的平方和再开方。 是不是看到这里就有点上头了,这个其实只是刚开始。对于一个给定的ADC来说,我们要去量化和测量它的这两个噪声,这样才能更好的...
The signal-to-noise ratio (SNR) of an ADC is the ratio of the signal power to the non-signal power. Non-signal power includes thermal noise, quantization noise, and other residual errors in the converter, measured in the Nyquist bandwidth (fSAMPLE/2) of the ADC. SNR is typically defined...

Thermal Noise Determine an ADC's Effective Noise Figure By: Daniel Terlep Sep 09, 2002 Abstract: The following application note provides an insight into the mathematical definitions of quantization and thermal noise, parameters which can significantly affect the signal-to-noise ratio (SNR) and ...
首先,在具体谈paper之前,先说说目前noise shaping SAR ADC的类型。按照NS的方式,即如何extract quantization noise和实现quantization noise的filtering,NS可分为CIFF(cascaded noise feedforward),EF(error feedback)以及两者的hybrid。CIFF和EF的具体区别,这里就不做具体解释了,有兴趣的可以去看看'[1]J. Fredenburg an...
