The main aim of this paper is to present solution of triple-input single-output (TISO) filter with independently adjustable pole frequency, quality factor, bandwidth and also gain. Filter is universal, operates in current mode and includes only one active element – so-called Controlled-Gain Voltage Differencing Current Conveyor (CG-VDCC) with two controllable parameters: transconductance (gm) and gain of output currents (BX). Implementation of CG-VDCC element in 0.18 um CMOS technology is also included and this model is used in proposed filter simulations.
