Six components were considered: thermal noise ([e.sub.nTR]) of the transducer and load resistance ([e.sub.nRL] or [e.sub.nRH]), amplifier voltage noise [e.sub.n] voltage generated by current noise [i.sub.n] on positive and negative input ([e.sub.ncRL-] or [e.sub.ncRH-] and [e.sub.nc-]) and
quantization noise ([e.sub.nQ]):
while Signal to
Quantization Noise Ratio (SQNR), representing the more indicative parameter for the quantizer performance assessment, is defined as [1-3]:
Allan variance method could be used to analyze the common five basic gyro noise terms, including angle random walk, rate random walk, bias instability,
quantization noise, and rate ramp.
More distinctively, transmitter and receiver non-linearities, phase noise, receiver
quantization noise, receiver Gaussian noise and channel estimation problems are also accounted.
Due to TDC finite resolution, it introduces
quantization noise on the output of synthesizer spectrum.
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.
The algorithm is developed as a solution to the problem of minimizing the overall
quantization noise when an analog signal is pulse code modulated.
This is because the fractional-N operation in steady state requires fractional spur reduction circuits whose
quantization noise folds into the PLL spectrum via loop nonlinearities, demanding more significant design efforts to minimize the loop nonlinearities.
