“…Utilization of the adjustable voltage gain (A) is also very useful in many cases, but complexity of active elements is worse [12] than basic structures utilizing g m or R x control [2,3]. Design of active elements in combination of several (at least two) types of control in frame of one active element is one of today's trends [13][14][15][16][17][18][19].…”

Presented research introduces active filtering circuits which allow change of the transfer type without necessity of reconnection of the input or output terminal that can be very useful for on-chip applications. Our attention is focused on simple first-order filters that allow high-pass response (HP), all-pass response (AP) and also direct transfer (DT) with constant magnitude and phase characteristics between two terminals (input and output) by adjusting of one controllable parameter (current gain B in our case). Useful modification of the well-known current follower transconductance amplifier (CFTA), the so-called Z-copy current-controlled current follower differential input transconductance amplifier (ZC-CCCFDITA) and adjustable current amplifier were utilized in these circuits. Interesting possibilities (crossing between several transfer functions) of presented circuits require different values of B to obtain desired transfer function that is very important for practice and selection of specific way of control. Requirements on value of this continuously controllable gain B differ among presented structures. Theory is supported by simulation and measurement results with behavioral models utilizing commercially available active elements and simulation results with active elements based on CMOS models.

“…Several active elements, based on transconductance section (OTA) [1,5] and current conveyor of second generation (CCII) [6,7], have been also proposed. For example, current conveyor transconductance amplifier (CCTA) [8] also utilizes independent R X and g m control in some of its variants, for example [9]. Modification of CCTA in [10] employs current gain control, where current conveyor with adjustable gain from X to Z terminal was used.…”

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 -the so-called Controlled-Gain Voltage Differencing Current Conveyor (CG-VDCC) with two controllable parameters: transconductance ( gm ) and gain of output currents ( B X ). Implementation of CG-VDCC element in 0.18 µm CMOS technology is also included and this model is used in proposed filter simulations.K e y w o r d s: current mode, SITO filter, universal filter, CG-VDCC
