“…amplitude A , constant time τ , and offset V os , are unknown, but they can be estimated by identifying the input exponential signal. The methods for identifying exponential signals include the least square method [1], prony‐like method [3], and maximum likelihood estimation [4]. The details of these methods are not introduced here, due to the length limitation of this Letter.…”

An accurate exponential histogram test (EHT) method is proposed for the ADC linearity test. Different from conventional EHT methods which estimate ADC static parameters only based on the number of hits, the proposed method accurately estimates the ADC transition levels, differential non-linearity and integral non-linearity by creative utilisation of the information of stimulus signal. As a result, the proposed method avoids the errors introduced by the assumed proportional relationship between the code width and the number of hits in conventional methods. Simulation results show that the proposed method outperforms the conventional methods in terms of accuracy and robustness.
