Hi, I found this equation for quantization noise in Analog Integrated Circuit Design by Tony Chan Carusone, David Johns and Kenneth Martin chapter 15 page 610 under the topic Quantization noise using determinis
Then, the concept of input-referred phase noise of an oscillator is introduced to evaluate the effects of thermal and flicker noise in a VCO-ADC in a similar way as in a conventional ADC. Finally, distortion and jitter in VCO-ADCs are analyzed from a system-level point of view.Gielen, ...
Quantization noise is inherent in the amplitude quantization process that occurs in the analog-to-digital converter (ADC). It is independent of the signal and can be modeled as additive noise, when the dynamic range has intensity levels ≥ 24 (equivalent to bit depth, B, of 4). For a ...
Noise Considerations The limiting factor in the resolution of an ADC is quantization noise (quantization error). Assuming that the quantization error is random it can be treated as white noise. The quantization noise power and RMS quantization voltage for an ADC is given by the equation: [4]...

Performance and Noise Floor in DFT Matlab File: afft_Quantization.m • Assume the effective clock rate (for either an ADC or a DAC) is arbitrarily fast • Without Loss of Generality it will be assumed that f SIG =50Hz • Index on DFT will be listed in terms of frequency (rather ...
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...
Quantization Noise Jayaram, working for Ittiam Systems of Bangalore, India writes [edited]: My mixed signal board contains a 12-bit ADC operating at 80MHz. I am characterizing the performance of this ADC. I am are using three pieces of equipment: ...
An analog-to-digital converter (ADC) works as a quantizer.The following figure illustrates an example for a quantization error, indicating the difference between the original signal and the quantized signal.Quantization NoiseIt is a type of quantization error, which usually occurs in analog audio ...
Hence, the power of quantization noise is related to the quantization step and given by (2.41)Eeq2=Δ212, where E( ) is the expectation operator, which actually averages the squared values of the quantization error [the reader can get more information from the texts by Roddy and Coolen (...
