Most of the work done on current conveyor based continuous time filters have been in either current mode or voltage mode domain. Architectures that can work in mixed mode may be useful from IC realization viewpoint and application adaptability. This paper proposes a generalized mixed mode universal filter configuration that may be used as voltage-input voltage-output or voltage-input current-output or current-input voltage-output or current-input current-output. The architecture uses minimum number of active and passive components reported till date and can realize all generic filter functions: low pass, band pass, high pass, notch and all pass. PSPICE simulation results agree well with theoretical values.
