Abstract :
New voltage-mode filter configurations using commercially available CFAs are investigated. The new configuration using two CFAs with positive feedback has very low sensitivities to the internal parameters of the CFAs, specifically, in the high frequency range. The theoretical analysis is verified using PSPICE simulations of the filter designs using the models for AD844 provided by Analog Devices Inc
