In this paper, a new generalized current-mode configuration for the realization of first-order all-pass, second-order all-pass and notch filter is proposed. The presented configuration uses single multi-output dual-X second generation current conveyor and two impedances. The configuration uses two grounded resistors and one grounded capacitor for the realization of first-order all-pass filter, and two resistors and two grounded capacitors for realizing second-order all-pass/notch filter. Furthermore, a band pass filter can also be realized by making slight modifications to the notch filter. In addition, a current-mode quadrature oscillator as an application of the proposed circuit of all-pass filter is also given. All the proposed circuits enjoy the feature of low input and high output impedance. Low input and high output impedance of the proposed configuration enables cascadability to all the circuits without additional buffers. The theoretical results are validated with PSPICE simulations using TSMC 0.18µm CMOS process parameters.
