摘　　要：为综合基于CCCCTA的接地回转器,根据CCCCTA的零-镜模型和接地回转器的节点导纳矩阵,利用节点导纳矩阵扩展法,实现了4个相互等效的接地回转器。导出的回转器具有两个特点,一个是通过调节CCCCTA的偏置电流,可以电控调节回转器的参数;另一个特点是电路仅使用单个CCCCTA。作为一个例子,通过使用导出的回转器之一,实现了一个极点频率为1.274 MHz、品质因素为4的带通滤波器。计算机仿真证明所导出的电路正确有效。In order to synthesize the grounded gyrator employing current controlled current conveyor transconductanceamplifiers（CCCCTAs）,according to eight alternative nodal admittance matrix（NAM）expansion equations as wellas 16 nullor-mirror models for the CCCCTA,Four alternative gyrators employing single CCCCTA are received byNAM expansion method. The derived grounded gyrators enjoy two features;one is that its parameter can be tunedthrough adjusting the bias currents of CCCCTAs,the other is only use of single CCCCTA component. As an ex-ample,a band-pass filter with fo=1.274 MHz,Q=4 is realized by using one of the derived grounded gyrators. Thecomputer simulations are included to verify the workability of the derived circuits.
