“…The universal filters encompose all types of filters such as low-pass, band-pass and band-stop to reduce the area of the chip. Universal filters also can be categorized into single-input single-output (SISO), multiple-input single-output (MISO) [8,9], single-input multiple-output (SIMO) [9] and multiple-input multiple-output (MIMO) [10]. Universal filters are an important building blocks in analog signal processing such as phase-locked loop FM stereo demodulation and touch-tone telephone tone decoding [11].…”

In this paper, a voltage mode multi input single output second order universal filter based on the voltage follower concept is proposed. The MISO filter offers low-pass, band-pass, high-pass, all-pass and band-stop filters which is digital selecting by the input. The filter design consists of positive feedback and feed forwards path to implement a universal filter. The positive feedback is used to increase the quality factor of the filter. The feed forwards path is necessary to create zeros for the band-stop and high-pass filter. The proposed filter has many advantages such as an electronically tunable filter response, low power consumption and area. The performance of the proposed design has been tested using CMOS 130nm process technology.

“…The maximum usable frequency range depends strongly on bias current, hence CCCII based implementations are expected to be better than OTA. The recently reported high output impedance universal current mode filter circuits having multiple outputs can be characterized as SIMO (single input multiple output) [2,[4][5][6][7] and MIMO (multiple input multiple output) [8][9][10]. The circuits [4][5][6]9] require component-matching condition to realize all universal filter functions whereas circuits [2,7] use floating capacitance that is not encouraged for monolithic integration [11,12].…”

“…[10] requires neither any component matching criterion nor floating capacitances but need extra hardware for current inversion to realize all pass response. The MIMO configurations [8][9][10] require additional hardware for providing extra inputs.…”

A new electronically tunable universal current mode biquad filter structure employing three multiple output current controlled conveyors (MOCCCII) and two grounded capacitors is presented. The proposed filter offers the following advantageous features: low input impedance and high output impedance-a desirable property of current mode filters; realization of low pass, band pass, high pass, notch, and all pass; no matching constraint; low sensitivity performance and use of grounded capacitors suitable for integration. The practical design problems due to nonlinearities of MOCCCIIs have also been addressed. The feasibility of the design is confirmed via SPICE simulations.

“…Current conveyors are proven their usefulness as building blocks because they enable the circuit designer to design circuits with higher linearity, lower consumption, higher frequency response and lower number of active elements [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. There are different types of current conveyors.…”

“…On the other hand, several analog filter realizations exist in the literature utilizing different types of active building blocks and each proposed circuit provides an additional property such as: no need for external resistors [2,3], electronically tuneability [4,5,6,7], low active-element count [7], providing lowpass, bandpass and highpass responses simultaneously [8], employing only grounded passive elements [9] and operation in true current-mode [1,10].…”

In this work, an electronically tuneable resistorless Kerwin-Huelsman-Newcomb (KHN) filter circuit is proposed, employing multi-output CCCIIs (MO-CCCIIs) and grounded capacitors,. The new circuit provides highpass, bandpass and lowpass responses simultaneously without any matching condition. Pole frequency and quality factor of the new circuit can be tuned electronically and orthogonally via biasing currents of MO-CCCIIs. SPICE simulation results verifying the theory are also included.
