全新倒Π型D/A权电容网络的设计

Design of Novel Inverter-Π Weightier-Capacitance Network of D/A

利用戴维宁定理求得一个倒Π型基本单元,进而用求和归一的方法得到"Π型D/A权电容网络"的改进形式即"倒Π型D/A权电容网络"。相比前者,该D/A权电容网络具有转换速度快和动态误差小的特点,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 inverter-Π is obtained by using Therenin theory, based on the reference,an improved form of Π network of D/A ,that is ,an inverter-Π weightier-capacitance network of D/A,is obtained by employing a method of summation normalization. In comparison with the former, the network has the advantages of higher velocity of translation and smaller error kinetics. Accordingly, the network is of important real significance and practical value in the field of electronic technology.
