Abstract
In this work, we propose a resistorless realization of a simple electronically adjustable capacitance multiplier circuit using a single voltage differencing gain amplifier (VDGA) as an active building block. The circuit utilizes one VDGA and only one capacitor in a simple circuit configuration. The proposed capacitance multiplier circuit can be tuned electronically with the adjustment of the transconductance gains of the VDGA. To emphasis the applicability of the proposed circuit, a second-order RC low-pass filter is constructed as an application example. PSPICE simulations are performed to verify the theory.
