Realization of R-L and C-D Impedances Using a Current-feedback Amplifier and Its Application

The integration of inductance is very difficult in the designing of integrated circuit.Therefore,it is necessary to imitate the inductance by using some circuit with power.The general way is using the electric current transmission machine to realize the RL/CD impedances electric circuit.However,the RL/CD impedances electric circuit which is based on the current-feedback amplifier are few.According to the related researching,by using the current-feedback amplifier and some passive component can carry out the RL/CD impedances electric circuits,and then realize the function of lowpass,bandpass and highpass filters.
