WebNov 1, 2024 · Figure 1 Non-linearity shows up in the form of integral non-linearity (INL) and differential non-linearity (DNL).Source: Texas Instruments Integral non-linearity (INL) measures how far the output strays off the ideal straight line. Differential non-linearity (DNL) measures the stability of the step width at each step across the range. WebDNL can be further reduced to improve the SNR by Grouping and Sorting method. 1. Introduction [1,2] DNL and INL are two important non-linearity errors of an ADC, which always leads to relatively severe loss of SNR. In this paper we will investigate how DNL and INL errors affect the SNR performance of an ADC, and study various methods

WebMay 1, 2024 · DNL (dynamic non-linearity) tells you that between two contiguous digital values (i.e. 10010000 and 10010001) the ACTUAL analogue voltage difference is not precisely 1 LSb. In your example of … Differential non-linearity is a measure of the worst-case deviation from the ideal 1 LSB step. For example, a DAC with a 1.5 LSB output change for a 1 LSB digital code change exhibits 1⁄2 LSB differential non-linearity. Differential non-linearity may be expressed in fractional bits or as a percentage of full scale. ...
