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.
