To obtain universal second-order current-mode filter with high accuracy,a voltage-mode Deboo integrator with VFA was turned into a current-mode Deboo integrator with AOA by means of the concept of adjoint network.A current-mod proportion circuit with multiple outputs was given by AOA.Finally,universal second-order current-mode filter using AOA s was realized.The pole frequency is 31.8 kHz,the quality factor is 1,and pass-band gain is 4.The circuit parameters rely on the resistance ratio,and two integrator c...
