Originální abstrakt
Two new circuits of 2nd order universal frequency filter designed using signal-flow graphs method are presented. Both filters were proposed in single-ended and fully-differential forms. Multiple-output current follower (MO-CF) and digitally adjustable current amplifier (DACA) used in proposal are described in the paper. The pole frequency and the quality factor of filters can be controlled by the current gain of digitally adjustable current amplifiers suitably placed in the circuit structure. The actual function of the proposed filters is verified using PSpice simulation. Simulation results of proposed filters are also included in this paper.
