Odjel za električne krugove i sustave bavi se teorijom, analizom, oblikovanjem (računalno potpomognuto oblikovanje), praktičnom primjenom krugova i primjena teoretskih metoda analize krugova na sustave i obradu signala. Ovo područje pokriva čitav niz aktivnosti od osnovne znanstvene teorije do industrijskih primjena.

Abstract— One of the problems with on-chip active-RC filters is that in order to satisfy tight specifications accurately, they need to be fine-tuned. This becomes more difficult with increasing filter order. In this paper, we introduce a simplified tuning method which is obtained by a new structure consisting of a filter section of second- or third-order (Biquad or Bitriplet which is referred to as a 'tuning block'), in cascade with a ladder-RLC filter (passive LC, or simulated-active RC). The cut-off frequency of the resulting filter can be simply tuned by adjusting one component of the tuning block. The new ladder tuning-block (LTB) is compared with two conventional structures, a cascade of Biquads and a single-ladder filter. Fine tuning these two structures is considerably more complicated. It is shown that beside the advantage of ease of tuning, the sensitivity to component tolerances of the new structure is lower than that of the two conventional ones, for the price of a slightly higher filter order.
