Abstract :
New second-order notch and allpass filters using a single current follower are proposed. The filters use five passive RC elements. Both the active and passive sensitivities are very low. The natural frequencies and the quality factors of the proposed filters are insensitive to the current tracking error of the current follower. Simulation results which agree with the theoretical analysis are obtained.
