This project is an attempt to design second - order RC - active filters using current mode circuits with minimum multiparameter sensitivity. Current activated circuits form an alternative approach to the more usual voltage activated ones where lower load impedances and large bandwidth may offer an operating advantage. The filters are implemented using either AD844 current conveyor or 3280 operational transconductance amplifier models, which are commercially available integrated circuits. At low frequency it is assumed that current mode circuits closely approximate their ideal models. However, this assumption will not remain valid at high frequency and the nonideal effects of current mode circuits must be taken into the design considerations.Large change sensitivity and differential sensitivity have been considered as a measure of circuit sensitivity relating to finite and infinitesimally small changes in circuit components respectively. In either type of sensitivity the Schoeffler criterion is used as a measure of multiparameter sensitivity. An optimization procedure is set up to obtain a minimum value of the multiparameter sensitivity criterion. The Complex Method is employed in the optimization runs in this thesis. The simulator program PSpice is used to verify that the circuits with the optimum values of the parameters satisfy the desired responses. Finally, the Monte Carlo technique was used to verify that the design after optimization is better than the one before optimization.
