Abstract
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.
