A new high input impedance voltage-mode universal biquadratic filter with three input terminals and six output terminals is
presented. The proposed circuit uses three plus-type differential difference current conveyors (DDCCs), three resistors, and
two grounded capacitors. The proposed circuit can realize all the standard filter functions, namely, lowpass, bandpass, highpass,
notch, and allpass, simultaneously, without component matching conditions. The proposed circuit still offers the features
of high input impedance, using only grounded capacitors, and orthogonal controllability of resonance angular frequency and

A new universal current-mode biquad with two inputs and three outputs or three inputs and two outputs using only two second-generation current conveyors and four grounded/virtual-grounded passive elements is proposed. The proposed circuit has the following advantages: simultaneous realization of five generic current-mode filter signals from the same configuration; no requirements of any cancellation constraints; employment of two grounded capacitors ideal for integrated circuit implementation; employment of two grounded/virtually grounded resistors suitable for voltage control; orthogonal adjustment of ω0/Q and ω0 through two separate grounded/virtually-grounded resistors; high output impedance good for cascadability for the current-mode circuits; and low active and passive sensitivities. 相似文献

Two new universal active current-mode filters are proposed, one topology of which is with three inputs and one output, the
other prototype is with single input and three outputs counterpart. One proposed circuit employs two current conveyors, two
grounded capacitors and two resistors, wherever the other proposed circuit employs two current conveyors, two grounded capacitors
and two multi-input, multi-output Operational Transconductance Amplifiers(OTA) as variable resistor for tuning the cutoff
frequency of realized filters. Without changing the passive elements, the proposed circuits employ features of multifunctional,
convenient for integration, low sensitivities and simple in structure. 相似文献

For the first time, a universal voltage-mode filter with three inputs and a single output has been realized by employing two 'grounded' capacitors in addition to two active current conveyors and two resistors. The proposed circuit offers the following advantageous features: simultaneous realization of voltage-mode low-pass, band-pass, high-pass, notch and all-pass filter responses from the same configuration; no requirement of critical component matching conditions; no requirement of inverting-type voltage input signal; employment of two grounded capacitors ideal for integration; and low active and passive sensitivity performance. H-SPICE simulation results confirm the theoretical analysis. 相似文献

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. 相似文献

A lossless floating inductance has been simulated using two differential voltage current conveyors, two resistors and one
grounded capacitor. The proposed floating inductance needs not component matching condition. Base on the proposed floating
inductance as building block, a new voltage-mode universal biquadratic filter with one input and five outputs can be obtained.
The proposed universal biquad uses two differential voltage current conveyors, three resistors and two grounded capacitors.
All standard filter functions; highpass, bandpass, lowpass, notch and allpass can be obtained, simultaneously, without changing
the passive elements. The proposed universal biquad has the features of using only grounded capacitors and orthogonal controllable

In this research article, a new third-order voltage-mode active-C asymmetrical band pass filter is proposed. It uses three numbers of current-controlled current conveyors and three numbers of equal-valued capacitors. The topology has the following important features: uses only three active elements, uses three capacitors, uses all grounded capacitors and no resistor is suitable for integrated circuit design, there is no matching constraint, high input impedance, low output impedance, central frequency can easily be electronically controlled by bias current, and frequency response is asymmetrical in nature. The application of the proposed topology in the realisation of a voltage-mode sixth-order symmetrical band pass filter has been demonstrated. The workability of the proposed topology and sixth-order filter has been confirmed by simulation results using 0.35-µm Austria Micro Systems complementary metal oxide semiconductor technology. 相似文献

Universal filter using plus-type CCIIs 总被引:1,自引:0,他引:1
A universal second-order filter circuit with voltage gain using only plus-type current conveyors (CCIIs) is presented. The circuit offers several advantages, such as high input impedance, low filter sensitivities to passive elements, use of grounded capacitors and independent control of ω0, Q and voltage gain with separate grounded resistors. The use of only one type (plus-type or minus-type) of CCII simplifies the configuration 相似文献
