摘要:
提出一种基于线性系统分析和仿真拟合的5阶数字Sigma-Delta调制器的设计方法.Simulink仿真结果表明:与过采样率为64的4阶调制器比较,所设计的5阶Sigma-Delta调制器在过采样率降低到只有32的情况下,输出信噪比可以达到104 dB,比前者改善了6 dB.因此,在相同过采样率下,该5阶调制器可以得到更宽的信号带宽.
Abstract:
This paper introduce a design method for the fifth-order digital Sigma-Delta modulator based on linear systems analysis and simulation fitting. Simulink simulation result shows that compared to the fourth-order modulator of oversampling ratio of 64, the oversampling ratio of the designed fifth-order modulator reduces to only 32, output signal to noise ratio can reach 104 dB, which improves 6 dB over the former design. Therefore, in the same oversampling ratio, this fifth-order modulator can get wider signal bandwidth.
