VDBA的零-镜模型及其在符号节点分析中的应用
Nullor-Mirror Models of VDBA and Applications in Symbolic Nodal Analysis
摘要
Abstract
To simplify the symbolic nodal analysis about the circuits employing voltage differencing buffered ampli⁃fiers(VDBAs),according to the terminal voltage-current constraints for the nullor-mirror elements as well as the ter⁃minal relations of the VDBA,12 nullor-mirror models for the VDBA and the related procedure of symbolic nodal analysis are presented in this paper. Furthermore,the proposed models are applied to a VDBA-based biquad filter and a quadrature oscillator to simplify nodal analysis process. The results show that the nullor-mirror models for the VDBA are systematic,effective and powerful in symbolic nodal analysis.关键词
