Cascadable voltage-mode all-pass filter with single DXCCII and grounded capacitor

A novel design of voltage-mode (VM) all-pass filter (APF) utilizing a single dual-X current conveyor (DXCCII) is proposed. Although many other voltage mode first-order APFs are available in literature, however majority of them cannot allow us to get high input impedance, low output impedance and grounded capacitor properties together. The proposed circuit offers these properties with reduced number of passive components. Experimental and SPICE simulation outputs are provided to validate the proposed theoretical result.
