Abstract :
The current-controlled second order multifunctional filter is described. It uses only three current controlled conveyors and two grounded capacitors. Three types of current transfers, highpass, bandpass, and lowpass, can be acheived simultaneously and both ω0, and Q are electronically adjustable. The circuit can also be modified to be a current controlled oscillator. The simulated results are illustrated
