This article is an attempt to present a tunable floating capacitance multiplier using commercially available integrated circuits, namely LT1228. The proposed design utilizes three LT1228s as active electronic components and only one capacitor as a passive component. The multiplication factor of the capacitancemultiplier is electronically tunable via adjusting the external supply currents of the LT1228s. Besides, a careful analysis of the parasitic element effects is also included. To verify the practical features of the proposed floating capacitance multiplier circuit, several simulations using PSPICE program tool and extensive laboratory measurements were performed.
