Abstract
Active configurations for simulating floating/grounded series and parallel immittance functions based on voltage differencing transconductance amplifiers (VDTAs) are proposed. The grounded series and parallel immittance simulators presented here require only one VDTA, while the proposed floating ones only need two. Each of the suggested simulators uses a single grounded capacitor. The proposed topologies can imitate R-L and R-C im-mittances in both series and parallel types. All of the simulated equivalent elements are electronically adjustable through the VDTA's transconductance. Furthermore, no component-matching restrictions are imposed in order to achieve the appropriate immittance function. Applications of the proposed VDTA-based immittance simulators include bandpass filter and quadrature oscillator implementations. The behaviors of the proposed circuits and their applications are evaluated by PSPICE simulations and experimental observations using VDTA implemented with commercially available CA3080 type OTAs.
