Abstract
In this paper, a new voltage mode universal filter topology is presented. The proposed topology can provide three circuits with all-pass, notch, band-pass, low-pass and high-pass filtering functions employing minimum number of active and passive components, namely a single first generation current conveyor, two resistors and two capacitors. Furthermore, these circuits obtained from general topology have dual outputs that can be used simultaneously. Sensitivities of the pole frequency and quality factor of the filter to the passive components can be made lower than unity in magnitude. Finally, natural frequencies of the presented circuits are independent from non-ideal voltage gain of the active element. Simulations are performed to verify the theoretical results.
