Single DDCC based new immittance function simulators employing only grounded passive elements and their applications

Two grounded immittance function simulators (IFSs) employing only grounded passive elements and one differential difference current conveyor are developed in this paper. Two floating IFSs are obtained from the grounded ones. A current-mode (CM) filter, a voltage-mode (VM) band-pass (BP) filter and a quadrature oscillator (QO) are derived from the first developed grounded IFS. However, for proper operation, all of the circuits except the BP filter and the QO in this study need a single resistive matching condition. Simulations of the CM and VM filter circuits as well as the QO are accomplished through SPICE program. Furthermore, as an example, so as to confirm the performance of the VM filter, an experiment is included.
