How is dnl calculated
WebIntroduction. The dynamic performance of an analog-to-digital converter (ADC) is determined by the effective number of bits (ENOB). In this application note, we examine the relationship of ENOB with other dynamic characteristics of ADCs such as signal-to-noise ratio (SNR), signal-to-noise and distortion ratio (SINAD), and total harmonic distortion … WebSome useful codes in Matlab with some considerations are available in my researchgates for INL and DNL

WebSignal-to-noise ratio (SNR, or sometimes called SNR-without-harmonics) is calculated from the FFT data the same as SINAD, except that the signal harmonics are excluded from …
The DNL is usually measured in LSb, although we can measure it as an absolute value (either volts or amperes) or as a percentage of the full-scale value. Integral Non-Linearity (INL) The INL is defined as the maximum deviation of the actual input-output characteristic from the ideal transfer characteristic. Meer weergeven A digital-to-analog converter (DAC) receives data represented as a digital code and produces an equivalent analog output (See Figure 1 below). The above ideal transfer … Meer weergeven The above model of a three-bit DAC in Figure 2 is too idealistic; in reality, there are many factors that limit the accuracy of the system. … Meer weergeven The INL is defined as the maximum deviation of the actual input-output characteristic from the ideal transfer characteristic. … Meer weergeven With the ideal transfer characteristic, if we increase the input digital code by one, the analog output should increase by the analog value corresponding to one LSb.
