Abstract
A floating general immittance function simulator circuit is presented using two differential voltage to current converters (DVTCs) and three passive components. The developed DVTC to be used in this work is realized with the flipped voltage follower, achieving low-voltage operation. By selecting proper passive components, the proposed floating simulator circuit can realize synthetic inductor, capacitor, resistor and frequency-dependent negative resistance (FDNR) without changing its configuration. No component matching conditions and cancellation constraints are necessary. Furthermore, non-ideal transfer gain effects on the proposed simulator circuit are discussed. As applications for the proposed floating simulator, a second-order RLC bandpass filter and a fourth-order resistively terminated LC bandpass filter are shown. To verify the theory, the proposed simulator and its applications are simulated using 0.25-μm CMOS process technology.
