Three simulated floating inductor (SFI) circuits containing a single DDCC− called as minus-type differential difference current conveyor are proposed. These SFIs are series lossy, parallel lossy and negative lossless ones. The used DDCC− in each of the proposed SFIs has a single Z terminal. Without needing any passive element matching constraints, each of the proposed SFIs is composed of a minimum number of passive elements. As application examples, second-order current-mode (CM) and voltage-mode low-pass (LP) filters derived from the proposed series lossy SFI are given. Also, a fourth-order CM Butterworth LP filter example is presented as another application. A second-order CM high-pass (HP) filter and an RLC resonant circuit obtained from the proposed parallel lossy SFI are given. All the simulations are achieved via SPICE program. Moreover, some experimental results for the proposed lossy SFIs and CM HP filter are given in order to show the performances.

基于单个DDCC的模拟浮动电感器及其应用

提出了三个模拟浮动电感器（SFI）电路，其中包含单个DDCC-，称为负型差分差分电流传输器。这些SFI为串联有损，并行有损和负无损。每个建议的SFI中使用的DDCC-具有单个Z端子。不需要任何无源元件匹配约束，每个建议的SFI都由最少数量的无源元件组成。作为应用示例，给出了从提出的串联有损SFI推导的二阶电流模式（CM）和电压模式低通（LP）滤波器。另外，另一个应用是四阶CM Butterworth LP滤波器示例。给出了从所提出的并联有损SFI获得的二阶CM高通（HP）滤波器和RLC谐振电路。所有仿真都是通过SPICE程序实现的。此外，
