| Summary: | The static parameters of analog to digital converter (ADC) include differential nonlinearity (DNL) and integral nonlinearity (INL). The main method to measure static parameters is the code density histogram method.The traditional code density histogram method has high requirements on the calculation accuracy of input sinusoidal amplitude. This paper proposes a normalized processing platform scheme based on code density histogram. According to the test requirements, the test excitation amplitude that meets the requirements is selected to verify the effectiveness of the normalized scheme.The experimental results show that normalization reduces the influence of sinusoidal amplitude change on the code density histogram method and improves the stability of the code density histogram method. |
