In this paper, a new general configuration for realizing current-mode all-pass filter circuits using differential voltage current conveyor (DVCC) is proposed. The proposed configuration is composed of a DVCC and five passive admittances. However, each of the circuits extracted from the proposed configuration uses only three passive elements. As an application, the proposed configuration is used to construct a quadrature oscillator. The theoretical results are verified by SPICE simulations.
