Nonlinear and noise macromodel of CMOS current conveyor

A macro model of second generation current conveyor (CCII) has been proposed. The model allows simulation of CCII frequency response, their noise and weakly nonlinear properties. The frequency dependencies of CCII transfer coefficients have been taken into account by means of inclusion to the macromodel of resonant- and RC-circuits. The nonlinear properties were described using nonlinear controlled sources, while the noise properties were described by two current and one voltage equivalent noise sources connected to CCII terminals. An accuracy of the proposed model has been verified by computer simulation and comparison of the results with simulation on the transistor level and experimental data.
