First-order voltage-mode all-pass filter providing high input and low output impedances is described. The proposed filter employs a fully-differential operational amplifier, a current-controlled current conveyor CCCII, and one capacitor, with the possibility of electronic control of natural frequency. Two voltage outputs are simultaneously available for non-inverting and inverting transfer functions, with the possibility of utilizing them as a differential output.
