中文摘要：
该文提出了一种新的通用高阶稳定的∑-△插值型A／D转换器的优化设计算法。该算法采用状态空间下通用的插值型结构，研究了设计原理和设计的详细过程，给出了传输函数变换和稳定条件，实现了零点优化和巴特沃思极点的噪声传递函数。在结构系数的实现中，采用能量增量最小的优化算法，使A／D转换器具有更佳的稳定性能。最后，通过例子验证了该方法的有效性。
英文摘要：
In the paper, a new general optimal design method of stable high-order interpolative ∑-△A/D modulator is presented. The design principle and process in detail are given by using an interpolative structure in state space and the transfer function conversion, then the noise transfer function is realized by optimized zero and Butterworth poles. The stable condition of modulator is studied and the structure coefficients are gained by minimizing the state energy in order to make the modulator more stable. Finally illustrative examples are demonstrated to show the effectiveness.
