Tunable mixed-mode OTA-C universal filter

Analog Integrated Circuits and Signal Processing, 2008
A novel electronically tunable mixed-mode universal biquad by using four single-output and one dual-output-operational transconductance amplifiers, two grounded capacitors is proposed. The proposed circuit has ability to realize voltage, current, transconductance, and transresistance mode, and can the following advantageous features: (i) realization of

Fully Digitally Programmable Generalized Mixed Mode Universal Filter Configuration

Circuits, Systems, and Signal Processing, 2015
This paper presents five feature-enriched hardware-efficient mixed mode universal filter (UF) biquads using digitally programmable (DP) current conveyors (CC). Common features of proposed UFs include use of only two grounded capacitors, operation in all the four modes, realization of all the filter functions, independently programmable filter ...

Mixed-Mode Universal Biquadratic Filter with No Need of Matching Conditions

Journal of Circuits, Systems and Computers, 2016
None 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 ...

New type of mixed modes dielectric cavity filter for multiplexers

17th AIAA International Communications Satellite Systems Conference and Exhibit, 1998
A 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.

A Current Tunable Mixed Mode ZC-CCTAs Based Resistor Less Universal Filter

Journal of Circuits, Systems and Computers, 2021
This paper introduces a novel current tunable biquad universal filter structure based on four Z-copy current conveyor transconductance amplifiers (ZC-CCTAs) and two capacitors. The proposed structure is a mixed mode topology that allows current and/or voltage signals at input and output terminals and can generate various biquad filtering responses ...

High-order mixed-mode OTA-C universal filter

AEU - International Journal of Electronics and Communications, 2009
Abstract 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.

Novel Electronically Tunable Mixed-Mode Biquad Filter

2011
This 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 ...

Single FDCCII-based mixed-mode biquad filter with eight outputs

AEU - International Journal of Electronics and Communications, 2009
Abstract The transconductance and the transresistance modes might act as the bridge transferring from voltage-mode to current-mode and vice versa, respectively. A novel mixed-mode (including voltage, current, transconductance, and transresistance modes) biquad filter with one input and seven outputs or two inputs and eight outputs is presented.

Mixed modes cylindrical planar dielectric resonator filters with rectangular enclosure

IEEE Transactions on Microwave Theory and Techniques, 1995
A 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.
