After giving six different forms of the extra X second-generation current-controlled conveyor(EXCCCII),pathological models of six EXCCCIIs are found by the nodal admittance matrix(NAM)expansion approach.Furthermore,these ideal pathological circuit models are employed and 36 Wien oscillators and 8 third-order quadrature oscillators are synthesized by the NAM expansion.The hand analysis and computer analysis are intro-duced to prove the synthesized circuits are correct and effective.
