First order voltage mode MO-CCCCTA based all pass filter

This paper for the first time presents a novel voltage mode (VM) resistor less first order all pass filter employing multiple-output current controlled current conveyor transconductance amplifier (MO-CCCCTA). The proposed circuit employs only one active element and one truly (not virtually) grounded capacitor. The angular pole frequency of the filter can be electronically tuned with the help of bias current. The proposed circuit is very appropriate to further develop into an integrated circuit. Sensitivity study of the circuit is provided and SPICE simulations have been included to verify the workability of the proposed circuit.
