Abstract
Disclosed are a device and method therefor for ENOB (effective number of bits) estimation for an ADC (analog-to-digital converter) based on dynamic deviation, wherein the correlation between dynamic deviation and ENOB is analyzed so as to provide a novel device and method therefor to estimate and calculate ENOB for an ADC. Dynamic deviation, provided in the present invention, can serve as a novel parameter for use in evaluation of the performance of an ADC. The present invention further provides a model related to the relation of distribution of dynamic deviation and input frequency, wherein ENOB can be therefore predicted for higher input frequency for an ADC without a high-quality signal generator by measuring dynamic deviation for lower input frequency.
