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 deterministic approach. Could someone please explain to me how they substitute Vlsb for Vq in the f...
ADC's effective bits specification provided the overall measure of system performance. The errors produced in ADC due to quantization were also measured. Th... G. Lang - 《Sound & Vibration》 被引量: 4发表: 2000年 Chapter 2 in Delta-sigma Data Converters Quantization Noise in A/d ...

In the previous article onquantization error for ADC converters, we observed that, for particular cases, the quantization error resembles a noise signal. We also discussed that modeling the error term as a noise signal can significantly simplify the problem of analyzing the effect ...
In systems with parallel analogue-to-digital converters (ADC), diversity combining can improve the signal to noise ratio (SNR) of the digitised signal. We consider a novel architecture, where the parallel ADCs operate on differently attenuated signals, in conjunction with maximal ratio combining and...
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]...
B-5-126 A Study on Nonlinear Equalization for Constant Envelope Phase Modulation Signals affected by Quantization Noise in ADC Orthogonal frequency division multiplexing (OFDM) is used in many wireless communication. The important drawback of this modulation is its high peak-to-average power ratio (...
In [11] the quantization noise and dynamic range are considered for compressive imaging (CI) systems design and evaluate the quantization depth requirements for CI, while the quantization error and the SFDR performance of CS are still undiscussed. Effects of ADC nonlinearity on the spurious dynamic...
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...
We analytically quantify the introduced distortion as a function of bit resolution and clipping ratio, both at the DAC and ADC. With this we provide a back-to-back signal-to-noise ratio analysis to predict the bit error rate of the system, assuming a fixed received optical power and ideal ...
