This paper presents a new current-mode universal filter with one-input three-output employing three translinear current conveyors and two grounded capacitors. The proposed filter provides low-pass, band-pass, high-pass current response with high output impedance output which can be directly connected for current-mode circuit. The band-pass and all-pass filters can also be obtained. The parameters wo and Q can be controlled separately and electronically by the bias currents of current conveyors. For realizing all filtering functions, no passive and active matching conditions are required. The active and passive sensitivities are low. The characteristic of the proposed circuit can be confirmed by SPICE simulations.

Circuit Configuration

The paper presents a new second-order single input multiple output (SIMO) type current mode (CM) universal filter. The proposed circuit uses two dual-X second generation multi-output current conveyors (DX-MOCCII), two grounded capacitors and three grounded resistors. The circuit configuration realizes low-pass filter (LPF), high-pass filter (HPF), band-pass filter (BPF), notch filter (NF) and all-pass filter (APF) responses simultaneously at different output terminals. The new circuit enjoys the features of low input impedance and high output impedance, which is desirable and useful for cascadability in CM circuits. For realizing the universal filter responses, the proposed circuit configuration does not require matching constraint of passive components and both active and passive sensitivities are found low. In addition, the extension of the proposed circuit as a resistorless universal filter has also been presented. As an application of the proposed filter, inverting band pass output is connected to a negative unity gain current follower in a close loop to design voltage and CM multiphase sinusoidal oscillators (MSOs). Comparison of the proposed configuration with available literature is given. The PSPICE simulation of the filter and its application as MSO are performed to verify the agreement with the theoretical proposition.

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.

In this paper, two new second-order voltage-mode universal filters are proposed. Both of the proposed filters use only two differential voltage current conveyors (DVCCs), four resistors and two grounded capacitors which are advantageous from integrated circuit technology point of view. They can simultaneously provide second-order low-pass, high-pass, band-pass, notch and all-pass responses. They offer orthogonal control of angular resonance frequency and quality factor. However, they have a single matching condition for only all-pass responses. A number of simulations based on SPICE program are accomplished in order to demonstrate the performance of both filters.

A current-mode first-order filter configuration simultaneously providing noninverting and inverting low-pass (LP) and high-pass (HP) responses depending on passive element choice is proposed. In addition, all-pass filter (APF) responses can be easily obtained with interconnection of LP and HP output currents. The proposed filter employs only two differential voltage current conveyors, a grounded resistor and a grounded capacitor, so it is suitable for integrated circuit realization. It provides the feature of high output impedance. It does not need any passive element matching constraints. A voltage-mode oscillator based on the inverting APF is presented as a typical application. The performance of the proposed configuration is verified through many SPICE simulation and experimental test results.

Four Terminal Floating Nullor

In this research paper, a voltage mode second order universal filter using Four Terminal Floating Nullor (FTFN) is presented. The proposed design uses Three Input Single Output (TISO) for the realization of all filter responses namely Low Pass Filter (LPF), High Pass Filter (HPF), Band Pass Filter (BPF), Notch Filter (NF) and All Pass Filter (APF) by using proper input selection. The analog building block, FTFN is simply realized with two commercially available AD844 ICs. The proposed second order universal filter comes with a single FTFN block with four passive components in which no component matching is required for filter realization. The universal filter is well verified using PSPICE simulation. In addition, experimental verification for the second order APF has been performed that confirms the theoretical expectations.
