Original Abstract

In this paper one new circuit of the 2nd-order multifunctional frequency filter designed using signal-flow graphs method is presented. New implementation of active element transimpedance amplifier (TIA) in non-differential form is used in this filter. Other active elements are multiple-output current follower (MO-CF) and multiple output transconductance amplifier (MOTA). The pole frequency and quality factor of the filter can be controlled mutually independently. Parameters of MOTA are used to control pole frequency and parameter of TIA is used for controlling of quality factor. This filter is designed as a multiple input multiple output (MIMO) with two inputs and six outputs. Functions of proposed filter are verified using PSpice simulation. Simulation results of proposed filter are included in this paper.

V tomto článku je prezentován nediferenční filtr druhého řádu navržený metodou grafů signálových toků. V tomto filtru je použita nová implementace aktivního prvku transimpedance amplifier (TIA) a to v nediferenční podobě. Dalšími použitými aktivními prvky jsou multiple-output current follower (MO-CF) a multiple-output transconductance amplifier (MOTA). U filtru je možné nezávisle přelaďovat mezní frekvenci a činitel jakosti. Prvky MOTA jsou použity pro změnu mezní frekvence filtru a prvek TIA je použit ke změně činitele jakosti. Filtr je navržen jako multiple input multiple output (MIMO) s dvěma vstupy a šesti výstupy.Funkce navrženého filtru jsou ověřeny v PSpice.
