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 grounding rotator based on CCCCTA, according to the CCCCTA zero-mirror model and the node admittance matrix of the grounding rotator, four equivalent ground rotators are realized by the node admittance matrix expansion method. Derived gyrator has two characteristics, one is by adjusting the CCCCTA bias current, you can electrically adjust the parameters of the gyrator; Another feature is the circuit using only a single CCCCTA. As an example, a bandpass filter with a pole frequency of 1.274 MHz and a quality factor of 4 was achieved by using one of the derived gyrators. Computer simulation proves that the derived circuit is correct and effective.
