A Fully differential current-controlled second generation current conveyor （FDCCCII） was proposed, The principle of the circuit was analyzed. The circuit has current-controlled function and can restrain even harmonics and common-mode signal. In 0-30 MHz, the simulation results show that the proposed circuit can meet the ideal port characteristic of FDCCCII. The power consumption of the FDCCCII is 5.69×10^-5 W, As an application, a differential current-controlled current-mode filter based on FDCCCII was realized and simulated.
