Abstract :
In the paper the author presents an approach to the synthesis of a complex converter for transforming a real coefficient lowpass filter transfer function into a complex-coefficient multipassband filter transfer function. For this purpose one applies a complex transformation on a suitably chosen driving-point reactance function, which can be realized by using switched-current (SI-) integrators. As a result the structure of a complex converter for synthesis of complex switched-current filters is obtained.
