一种全新的倒Π型D/A权电阻网络

A New Inverted Π Weighter Resistor Network of D/A

利用戴维宁定理求得一个倒Π型基本单元，进而用求和归一的办法得到“Π型Ｄ／Ａ 权电阻网络”的改进形式“倒Π型Ｄ／Ａ 权电阻网络”．相比前者，该网络具有转换速度快、动态误差小的特点，使其在电子技术应用领域有重要的现实意义和实用价值．

A basic unit of inverted Π is obtained by using Therenin theory based on the reference[1], and an improved form of Π network of D/A, that is, an inverted Π weighter resistor network of D/A, is got by employing a method of summation normalization. The network has the advantages of higher velocity of translation and smaller error kinetics. It will be practical and valuable in the field of electronic technology.
