Abstract :
A novel method of transformation of op.-amp.-based circuits to adjoint ones based on CCII´s is presented. The new method relies on an adjoint CCII-based subcircuit of the op. amp. feedback-impedance elementary structure. The proposed subcircuit can directly replace op. amps. with feedback impedance in a filter and transform it to an adjoint with high frequency capabilities. Application to Friend-Deliyannis biquad and PSPICE simulation verify the correctness of the method
