Mixed-mode universal filter using MCCCII

AEU - International Journal of Electronics and Communications, 2009
Abstract A novel mixed-mode biquad filter based on MCCCIIs (multiple outputs current controlled conveyors) is presented. The filter structure presented simply contains five MCCCIIs, two grounded capacitors and can realize low-pass, high-pass, band-pass filter functions from the same topology, simultaneously.

MIXED MODE UNIVERSAL FILTER

Journal of Circuits, Systems and Computers, 2013
The configuration with electronic tunable characteristics that can work in mixed mode may be useful from IC realization viewpoint and application adaptability. This paper proposes an electronically tunable mixed mode universal filter based on multiple output current controlled current conveyor (MOCCCII) and this single topology without any alteration ...

Mixed Mode Filters (Short Papers)

IEEE Transactions on Microwave Theory and Techniques, 1974
Mixed mode bandpass filters are described which utilize alternating TE/sub 011//spl deg/ and TE/sub n11//spl deg/ circular waveguide cavity modes. This novel filter configuration exhibits both excellent unloaded Q and spurious mode response characteristics.

Mixed modes dielectric resonator filters

IEEE Transactions on Microwave Theory and Techniques, 1994
A new configuration of dielectric loaded cavity filters is presented. The filter combines the superior spurious free performance of TE/sub 01/ mode ring dielectric resonators with the advantage of HE/sub 11/ dual-mode dielectric loading. Resonant frequency, field distributions and unloaded Q of each cavity are computed by rigorous mode-matching ...

Mixed-Mode Universal Biquad Filter Using OTAs

Journal of Circuits, Systems and Computers, 2019
This paper introduces an electronically tunable mixed-mode universal biquad filter configuration employing four single output operational transconductance amplifiers (OTAs), one dual output OTA and two grounded capacitors (GCs) (ideal for integrated circuit implementation and absorbing shunt parasitic capacitances). The presented structure can realize

Mixed-mode continuous-time video acquisition filters

Proceedings of IEEE International Symposium on Circuits and Systems - ISCAS '94, 2002
As an alternative to the usual purely analog antialiasing filters, a mixed mode approach is studied, and the existence of a continuous-time representation is recalled. Using a slight oversampling of a factor of two typically, the specifications of the analog filter can be relaxed and its sensitivity can be significantly reduced.
