A novel mixed-mode current-conveyor-based filter
International Journal of Electronics, 2004A new mixed-mode biquad circuit is presented. The circuit uses six single-output plus-type second-generation current-conveyors (CCII+s), a single dual-output CCII+, two grounded capacitors, eight resistors, at least two of them permanently grounded, and can realize lowpass, highpass, bandpass, notch, lowpass notch, highpass notch and allpass responses ...

Mixed-Mode Universal Biquadratic Filter with No Need of Matching Conditions
Journal of Circuits, Systems and Computers, 2016None of the previously reported mixed-mode universal filters can achieve the following important advantage: no need of component matching conditions. This paper presents a new mixed-mode (including voltage, current, transadmittance, and transimpedance modes) universal biquadratic filter with no need of matching conditions (including no need of ...

Novel Electronically Tunable Mixed-Mode Biquad Filter
2011This paper presents a novel electronically tunable mixed-mode biquad filter. The proposed filter employs only three multi-output current controlled current conveyor trans-conductance amplifiers (MO-CCCCTAs) and two grounded capacitors. With the current as an input, the proposed filter can realize low pass (LP), band pass (BP), high pass (HP), band ...

High-order mixed-mode OTA-C universal filter
AEU - International Journal of Electronics and Communications, 2009Abstract The transconductance and the transresistance modes might act as the bridge transferring from voltage mode to current mode and vice versa, respectively. This brief presents a universal mixed-mode high-order OTA-C filter structure using n + 1 single-output OTAs, one multi-output OTA, and n grounded capacitors.

New type of mixed modes dielectric cavity filter for multiplexers
17th AIAA International Communications Satellite Systems Conference and Exhibit, 1998A new configuration of mixed mode cavities is shown to be the basic building block in advanced filter designs providing the realisation of arbitrary filter functions with low loss and excellent spurious performance. It demonstrates the utilisation of dual or multi mode cavities without the need of coupling discontinuities (e.g.

Mixed-mode S-Parameter Characterization of a Distributed-based Transversal Filter
2005 2nd International Conference on Electrical and Electronics Engineering, 2005A transversal filter based on distributed amplifier principles is characterized in the frequency domain. It is shown that mixed-mode s-parameters provide a judicious characterization of a filter structure which has the ability of transmitting simultaneously signals in several modes of propagation (mixed-mode propagation).

Digitally programmable current-conveyor based mixed-mode universal filter
International Journal of Electronics Letters, 2014This paper presents a novel mixed-mode universal filter (UF) using digitally programmable second-generation current conveyor. The proposed single filter configuration is capable of realising all the standard filter functions in both inverting and non-inverting forms in all the four modes, namely voltage mode, current mode, trans-impedance mode and ...

Mixed modes cylindrical planar dielectric resonator filters with rectangular enclosure
IEEE Transactions on Microwave Theory and Techniques, 1995A compact mixed modes cylindrical planar dielectric resonator filter in rectangular enclosure with excellent spurious free performance is presented. Space coupling between different mode's dielectric resonators and iris coupling between identical mode's dielectric resonators are realized in the filters.
