Integral non … WebFeb 12, 2024 · DNL is calculated as: DNL ( i) = V out ( i + 1) − V out ( i) ideal LSB step width − 1. Integral nonlinearity is the deviation of a particular output code from the ideal. For example, if your 12 Bit ADC has an INL of 10 LSBs, you know that the output it reports is always within 10 / 2 12 = 0.25 % of the “true” output code.

DAC: non-linearity, non-monotonicity and midpoint glitches

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.

WebThe Integral Non-Linearity is defined as the maximum deviation of the ADC transfer function from the best-fit line. An ADC function is to digitize a signal into a stream of digital words called samples. The ADC output is discrete as opposed to the input, which is continuous. It is used at the boundary between the analog and digital realms. WebThis paper presents a theoretical nonlinearity analysis of R-2R ladder-based current-steering digital to analog converter (DAC). Besides the current mismatches, this paper analyzes static nonlinearity caused by resistor mismatches in the R-2R ladder.
