Abstract in different language: This contribution present way how to improve the finite attenuation in the stop band in the case of particular transfer function of the specific filtering structure. It is an important problem in the field of active filters. Real non-ideal model (including small-signal parasitic influences caused by real active elements) of the electronically reconfigurable reconnection-less filter is studied in configuration when the most affected transfer function is used (high-pass response in our case). Symbolical analyses of ideal and influenced transfer function and sensitivity analyses in Matlab provide information how to improve level of stop-band attenuation by available parameters even under condition of really unsuitable terminal resistances (output resistances) of active elements used.
