Originální abstrakt

Four adjustable band-pass filtering solutions are presented and also compared in this paper. Two of them are suitable for single-ended signal processing and the other two are their fully-differential equivalents. Filters are built with two types of active elements. First is a simple current follower with multiple outputs and second is a current amplifier with adjustable current gain that is used to control the quality factor of each of filters. Dependency between gain and quality factor is direct in two cases or inverse in other cases and that is why the range of adjustability varies. Simulations with CMOS-transistor structures are included. Values of quality factor obtained for each of solutions are assessed.
