了解SINAD、ENOB、SNR、THD、THD + N、SFDR，不在噪底中迷失。用于定量表示ADC动态性能的常用指标有六个，分别是：SINAD(信纳比)、ENOB(有效位 数)、SNR(信噪比)、THD(总谐波失真)、THD + N(总谐波失真加噪声)和SFDR(无杂散动态 范围)。(Learn SINAD, ENOB, SNR, THD, THD+ N, SFDR, lost not noise floor. For quantitative expression commonly used indicators of the dynamic performance of the ADC six are: SINAD (SINAD), ENOB (effective number of bits) and SNR (signal-to-noise ratio), THD (total harmonic distortion), THD+ N ( The total harmonic distortion plus noise) and SFDR (spurious-free dynamic range).)
