At present, modern active elements together with the utilization of the synthesis method based on purposefully lossy RLC prototypes enable us to realize ARC filters (for the frequency range within units of MHz) applying simple and economical selective building FDNR blocks that successfully work with one active element (OZ). This research report contains a complex analysis of attributes characterizing lossy active functional blocks; the authors show that the connection of active blocks with a series substitute model is significantly more advantageous than the commonly used parallel substitute scheme solution. A substantial benefit brought by this type of connection consists in the fact that, at higher frequencies, it does not exhibit the parasitic transmission zero which causes considerable problems in the case of parallel connections. Other related advantages of the described solution can be seen in its lower sensitivity to real parameters of the active elements, lower sensitivity to the variation of impedance level, and signicantly higher (up to 20 dB) attainable circuit dynamics.
