摘　　要：By the aid of nullor-mirror models of the second-generation current-controlled conveyor(CCCII) and applying the nodal admittance matrix(NAM) expansion method, the family of current-mode Colpitts oscillators employing four CCCIIs and three grounded capacitors is synthesized. Thirty-two Colpitts oscillators using CCCIIs are obtained in all. By using canonical number of components, the circuits can be easily integrated and the oscillation criterion and the oscillation frequency can be independently and electronically tuned by tuning bias currents of the CCCIIs. The paper-and-pencil analysis and Pspice simulation results have been included to support the synthesis method.By the aid of nullor-mirror models of the second-generation current-controlled conveyor(CCCII) and applying the nodal admittance matrix(NAM) expansion method, the family of current-mode Colpitts oscillators employing four CCCIIs and three grounded capacitors is synthesized.
