Abstract
Aiming at the measurement of effective bits of A/D converters,a method based on sinusoidal distortion measurement is presented,and the calculation formula is given out. One can realize the calibration of effective bits of A/D converters without complicated sinusoidal curve-fitting. When A/D bit varying from 3 bits to 24 bits,and sampling rate to frequency ratio is varied,by using a group of simulation,the measurement method is compared with the sine wave curve-fitting method. The results show that,the sinusoidal curve-fitting method fit for more cases,but the method is more simple and easy. Through a group of experiments,both the feasibility and correctness of the method in this paper are proved.关键词
