Abstract: Two voltage-mode high input impedance differential input-differential output first-order allpass filters based on differential difference current conveyor (DDCC) are presented. Each of the proposed circuit uses one plus-type DDCC, one grounded capacitor and three resistors. The proposed circuits enjoy the features of high input impedance, tunable of the allpass gains and using only grounded capacitors. The tracking error and sensitivity analysis of the proposed circuits are given. Simulation results confirm the theoretical analysis.
