摘　　要：本文用双图法,根据有源器件的RC-nullor模型,详细推导了计算Z-nullor线性反馈放大器的网络函数、广义回归差、广义零回归差以及相对灵敏度函数的基本回路阻抗矩阵公式,并对某些参数作出了物理解释。文中的公式与根据有源器件的受控源模型导出的公式很相似。On the basis of RC-nullor models of active devices in this paper, the fundmental loop-impedance matrix formulae of calculating network functions, generalized return difference, generalized null return difference and relative sensitivity of Z-nullor linear feedback amplifiers are derived in detail by using dual graphics. The physical interpretation of some parameters in given also. It is shown that there exists a strong similarity between the formulae derived in this paper and those based on controUcd source models of active devices.
