Abstract
A method of determining Integral Non-Linearity (INL) of an Analog-to-Digital Converter (ADC) is provided. The method includes providing an input signal to the ADC, phase-locking a clock signal of a clock of the ADC to the input signal, generating a plurality of samples at a sampled phase on the input signal for a plurality of sampled phases, applying averaging to the plurality of samples for each sampled phase to generate a reconstructed ADC output signal, and determining the INL of the ADC based on a comparison of the reconstructed ADC output signal to a theoretical ADC output signal.
