Two new CMOS realization circuits of current-controlled second generation current conveyor (CMOS CCCII) based on compound MOS translinear loop and MOS current mirrors is proposed. The circuit can satisfy port characteristic without need for restriction conditions which relate to fabrication parameters, so the difficulties of design and fabrication can be decreased. It presents such advantages as easy realization in the fabrication, simple circuit configuration, wide bandwidth, low power consumption and so on. The principle of the circuit is analyzed in detail. PSPICE simulation results for the proposed circuit in 0.5 mum CMOS technology is included. In the frequency range of 0~20 MHz, the simulation results show the proposed circuit meet ideal port characteristic of CCCII.
