摘　　要：无源LC梯形网络的综合已经形成了一套完美的理论和方法。而对有源RC网络的综合却研究的不多。文中基于节点导纳矩阵主元扩展理论,用给定的符号电压传递函数,给出了两个新的低通和带通二阶有源RC滤波器电路的综合方法。电路的仿真结果验证了有源网络综合理论在滤波器设计中的可行性。The theory and methods of synthesis of passive LC ladder network are elegant.However,not much attention has been paid to the synthesis of active network.Based on theory of nodal admittance matrix pivotal expansion,two new 2nd-order active-RC filter circuits that are lowpass filter and bandpass filter are derived from a given symbolic voltage transfer function.The simulation result verifies the active network synthesis theory in active-RC filter design.
