摘要
在单级多比特Σ Δ(增量 总和 )调制电路中 ,内部的ADC和DAC的结构规模和精度都会对调制器的性能有很大的影响 .文中探讨能够减小内部ADC量化器规模的调制器新结构 。
In the single-stage multi-bit Σ-Δ modulating electronic circuit,the structure scale and accuracy of the internal ADC and DAC have a profound impact on the function of modulators.A new modulator structure is proposed,which can decrease the scale of the internal ADC.Futhermore,the new function is compared with that of other previous structures and algorithms.
