本文将量化器等效为增益可变的加性噪声模型，研究了１ｂｉｔ高阶∑△调制器的稳定性，提出了一种设计１ｂｉｔ稳定高阶（＞２）∑△调制器的方法，该方法简单有效。
In this paper, the quantizer is equivalent to a variable gain additive noise model. The stability of a 1bit high order ΣΔ modulator is studied. A method to design a 1bit stable high order (> 2) ΣΔ modulator is proposed. The method is simple and effective.
