A new study imitating the design and implementation of single-input–single-output (SISO) filters as bilateral filters has been presented in this paper. Second generation current controlled current conveyor (CCCII), being a popular low power active element was considered for the realization of the proposed design. Complete design, analysis and implementation of the voltage mode SISO filter was done using only two CCCII’s and two passive parasitic components. The striking feature of this work is that the proposed design can be made to work at either the input node or the output node, as well as in the cases; the change of direction changes the filter into an inverse filter and buffer filter. Basic filter applications like low-pass, high-pass, band-pass and band-stop were aimed to check the uniformity of the proposed design at different frequencies. Results perceived from the simulation study were fare enough on both the side nodes of the proposed design. Categorically, the circuit can be aimed to work in lieu of a filter transceiver. The consistency of the circuit was analyzed by the nodal analysis. Whereas the working performance was enormously analyzed and evaluated during the simulation analysis. The proposed design was simulated in HSPICE tool to exhibit and exploit the delivery, using the 45[Formula: see text]nm predictive technology model (PTM) parameters, with [Formula: see text][Formula: see text]V rail to rail voltages. Maximum power consumption of the circuit is around 138.5[Formula: see text][Formula: see text]W. Finally, the design was also implemented in Cadence Virtuoso using 40[Formula: see text]nm SMIC parameters.

A novel voltage-mode universal filter employing only two current differencing buffered amplifiers (CDBAs) is proposed. The filter uses four inputs and single output to realize six responses, viz. low-pass, high-pass, inverting band-pass, noninverting band-pass, band-elimination, and all-pass through input selection with independent pole-Q control. Computer simulation results using SPICE are also given to verify the theory.

The objective of this study is to present four new universal biquad filters, two voltage-mode multi-input-single-output (MISO), and two current-mode single-input-multi-output (SIMO). The filters employ one voltage differencing current conveyor (VDCC) as an active element and two capacitors along with two resistors as passive elements. All the five filter responses, i.e., high-pass, low-pass, band-pass, band-stop, and all-pass responses, are obtained from the same circuit topology. Moreover, the pole frequency and quality factor are independently tunable. Additionally, they do not require any double/inverted input signals for response realization. Furthermore, they enjoy low active and passive sensitivities. Various regular analyses support the design ideas. The functionality of the presented filters are tested by PSPICE simulations using TSMC 0.18 µm technology parameters with ± 0.9 V supply voltage. The circuits are also justified experimentally by creating the VDCC block using commercially available OPA860 ICs. The experimental and simulation results agree well with the theoretically predicted results.

Two new minimum passive component oscillators using inverting current conveyor (ICCII–) acting as a voltage negative impedance converter are generated from the Sallen Key low-pass and high-pass filters. It is also shown that the Sallen Key low-pass, high-pass, and band-pass filters are the origin of the three minimum component oscillators using the current conveyor acting as a current negative impedance converter. In addition, it is also shown that the Sallen Key high-pass and band-pass filters are the origin of the two minimum component oscillators using single input single output transconductance amplifier as the active element. Although this paper is considered partially a review paper it includes new generation methods and new minimum component oscillator circuit realizations. Simulation results for the new oscillators using ICCII– are included.

The paper introduces a new versatile universal biquadratic configuration based on two fully differential second generation current conveyors without need of input matching conditions. The proposed circuit consists of two fully differential second generation current conveyors, four resistors and two grounded capacitors. The proposed biquad configuration provides all five standard filtering responses: low-pass, high-pass, band-pass, band-reject and all-pass in voltage-mode, transadmittance-mode, current-mode and transimpedance-mode. The proposed circuit is single-input multiple-outputs type, so all responses are available simultaneously. Moreover, extra inverting amplifier and double-type amplifier are also not required in the proposed circuit for any filtering response. The nonideal and parasitic effects of fully differential second generation current conveyor on the proposed circuit have also been investigated. HSPICE simulation results have been incorporated to validate the proposal.

This filter circuit can be used for different merit factor (Q) with high pass band gain. This gives better stop-band attenuation and sharper cut-off at the edge of the pass-band. Thus the response shows wider pass-band. The Ideal value of this filter circuit which is closed to Ideal value of third-order active-R filter is at 0.8? Q ?6. The advantages of this circuit are reduction in size and weight, increased circuit reliability, more economical and easy for manufacturing.

In this paper, a universal current-mode second-order active-C filter for simultaneously realizing low-pass, band-pass and high-pass responses is proposed. The presented filter employs only three plus-type second-generation current-controlled conveyors (CCCII+s). This filter needs no critical active and passive component matching conditions and no additional active and passive elements for realizing high output impedance low-pass, band-pass and high-pass characteristics. The angular resonance frequency (ω0) and quality factor (Q) of the proposed resistorless filter can be tuned electronically. To verify the theoretical analysis and to exhibit the performance of the proposed filter, it is simulated with SPICE program.
