The characteristics of ADC quantization nonlinearity under a signal in colored noise are analyzed.Analytic method and theoretical explanation are given.Our research shows that ADC quantization
under the condition of low SNR
has its own regulation.Using the test method presented by this paper
test result of accumulation can correspond to any tidy change of input signal.So we can get higher resolution based on primary high resolution ADC.We also can improve the system design of weak signal detection.At last
we point out that it's necessary to test the characteristics of ADC quantization nonlinearity under the condition of low SNR for engineering application.
