Abstract :
An active-RC realization scheme of a third-order Butterworth function in the current mode, using the second-generation current conveyor (CC II) active elements and with all equal-valued passive components, is proposed. With nonideal CC II´s, some of the coefficients of the function are altered owing to the finite port current and voltage tracking errors of the device. The network parameters are practically insensitive to the device errors
