sfdr meaning in Chinese

无杂散动态范围

The sfdr and thd are up to 68db and - 61db . the inl and dnl are smaller than 0 . 5lsb . the structure of the converter is improved based on traditional one so that the area of glitch is reduced sharply and the dynamic character is improved
在电路结构上,提出了单位电流源中的开关差分控制信号交叉点的最优值,并在差分开关上叠加一对常开pmos管,有效减小了输出毛刺面积,改善了动态性能。
The slope signal analyses and sinusoidal signal analyses show that the dnl 1 / 2lsb , at 49 . 902 mhz input frequency and 100mhz sampling frequency , sfdr is 75 . 5db and the or output can detect correctly whether the input signal is overflow and the system has good linearity
输入频率为49 . 902mhz的满幅( 500mv )正弦信号,测得adc的无杂散动态范围( sfdr )为75 . 5db ,系统的具有良好的线性度。
