Current Controlled CCTA Based- Novel Grounded Capacitance Multiplier with Temperature Compensation

This article introduces a grounded capacitance multiplier employing current controlled current conveyor transconductance amplifiers (CCCCTAs). The provided capacitor is a grounded element. Its outstanding feature is that the capacitive value can be electronically adjusted by input bias currents of the CCCCTA and is temperature-insensitive. The circuit construction comprises two CCCCTAs, cooperating with a grounded capacitor. The circuit performances are depicted through PSPICE simulations, they show good agreement to theoretical anticipation. Application as a fifth-order Chebyshev low-pass filter is included.
