“…Current-mode (CM) signal processing circuits received considerable attention because this technique offers several advantages compared to voltage-mode (VM) signal processing circuits, such as greater signal bandwidth, wider dynamic range and especially simpler circuitry [27], [28]. Considering the universal filters in , the circuits in [3][4][5][6][7][8][9][10][11][12] are VM filters while the circuits in [13][14][15][16][17][18][19][20][21][22][23][24][25][26] are CM filters. This paper is focused on the CM filters which are supposed to use only a single active device and grounded capacitors.…”

A new electronically tunable current-mode multifunction universal filter with three inputs and one output based on current-controlled current follower transconductance amplifier is presented. The proposed filter can implement low-pass, band-pass, high-pass, band-stop and all-pass transfer functions with a single topology. For implementation of these transfer functions, no passive component-matching conditions, no inverted input signal requirements and high-output impedance are required. Also the proposed filter offers electronic control of the natural angular frequency, low active and passive sensitivities and use of grounded capacitors which is ideal for integrated circuit implementation. The proposed universal biquadratic filter has been used for implementing sixthorder filters. PSPICE simulation results confirm the presented theory.

Abstract-This paper presents a new electronically tunable voltage-mode universal biquad filter based on simple CMOS operational transconductance amplifiers (OTAs) and grounded capacitors. The proposed filter provides second-order lowpass, bandpass and highpass voltage responses at a high impedance input terminal, which enable easy cascadability. The circuit enjoys realization using a low number of active and passive components, no requirement with the component choice conditions to realize all filtering functions, and low active and passive sensitivities performance. The performances of the proposed filter are simulated with PSPICE to confirm the presented configuration.Index Terms-voltage-mode filter, electronically tunable, operational transconsconductance amplifier, CMOS
