Floating capacitance multiplier using DVCC and CCCIIs

This article introduces a floating capacitance multiplier employing differential voltage current conveyor (DVCC) and second generation current controlled current conveyors (CCCIIs). The provided capacitor is a floating element synthesized from a grounded capacitor. Its outstanding feature is that the capacitive value can be electronically adjusted by input bias currents of the CCCIIs and is temperature-insensitive. The circuit construction comprises one DVCC and two CCCIIs, cooperating with a grounded capacitor. The circuit performances are depicted through PSPICE simulations, they show good agreement to theoretical anticipation. Capacitance increasing and an application as a fifth-order Chebyshev high-pass filter are included..
