Small-Signal Calculation of Common-Mode Choke Characteristics Using Finite-Element Method

IEEE Transactions on Electromagnetic Compatibility, 2015
This paper presents a finite element method approach to calculation of the common mode choke impedance over a wide frequency range. The proposed method involves a 3D electrostatic finite element calculation of each turn-to-turn and turn-to-core capacitance, and their usage as electric circuit lumped parameters in the 3D time-harmonic magnetic finite ...

Wideband crosstalk interference cancelling on xDSL using adaptive signal processing and common mode signal

2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004
Crosstalk originating from multiple high-speed data services in the same telephone bundle is a limiting factor for the maximum bit rate, the loop length and the number of data services that a bundle can support. Due to the nature of twisted-pairs, external interferences (including crosstalk) mostly couple to the twisted-pair line in common mode, and ...

A novel wideband common-mode suppression filter for differential signal transmission

2014 IEEE Electrical Design of Advanced Packaging & Systems Symposium (EDAPS), 2014
A novel wideband filter is designed for common mode noise (CMN) suppression in high-speed differential signaling. The dumbbell-shaped defected ground structure (DGS) is periodically etched in the return path of differential line to suppress CMN. In order to improve the signal quality of the differential transmission, a periodic stub-loaded structure is

A Wideband Microstrip Common-Mode Suppression Filter Using Signal Interference Techniques

IEEE Microwave and Wireless Components Letters, 2017
A fully-planar common-mode (CM) suppression filter is presented. Because of destructive interference between two different CM signal paths, multiple transmission zeros are created to reject CM signals. The positions of transmission zeros can be controlled, and the desired rejection level and wide stopband can be obtained by adjusting the ...

A novel HU-shaped common-mode filter for GHz differential signals

2008 IEEE International Symposium on Electromagnetic Compatibility, 2008
A novel low-cost filter design for common-mode noise suppression in high-speed differential signals is proposed. It is realized by etching a HU-shaped defected-ground structure (DGS) to perturb the return current of the common-mode noise. A simple LC resonator model for the proposed structure is also developed with good agreement to the full-wave ...

A novel broadband common-mode filter for high-speed differential signals

2008 Asia-Pacific Symposium on Electromagnetic Compatibility and 19th International Zurich Symposium on Electromagnetic Compatibility, 2008
A novel low-cost filter design for common-mode noise suppression in high-speed differential signals is proposed. It is realized by periodically etching the dumbbell-shape defected ground structure (DGS) to perturb the return current of the common-mode noise.

Cancellation of common-mode output signal in Class-BD audio amplifiers

2016 International Conference on Signals and Electronic Systems (ICSES), 2016
In the paper new topologies of the Class-BD amplifiers with Common-Mode (CM) free outputs have been presented. They are composed of the typical H-bridge output stage with four MOSFETs controlled by the optimal NBDD PWM signals and two additional switches separating the H-bridge from the power supply during the time intervals in which either high-side ...

Wideband common-mode suppression filter design for multi differential signal pairs

2015 Asia-Pacific Symposium on Electromagnetic Compatibility (APEMC), 2015
In this paper, we proposed a wideband common-mode suppression filter for multi differential signal pairs. The method of the proposed design is utilized by using Defected Ground Structure (DGS) of two quarter-wavelength resonators with the mutual coupling effect to achieve the wideband common-mode suppression.

Controlling common mode noise radiation through differential signalling IO buffer optimization

2013 IEEE International Symposium on Electromagnetic Compatibility, 2013
Non-ideal IO differential signaling from the silicon die or transmitter buffer propagating through the package, printed circuit board, connector, cable until to the external device, may cause undesirable common mode noise radiation. This common mode noise could be radiated effectively through the external cable causing the risk of EMI.

Reduction of Common-Mode Noise in Bent Differential Interconnects for PAM4 Signaling

2019 Electrical Design of Advanced Packaging and Systems (EDAPS), 2019
A wideband common-mode (CM) suppression filter for bend discontinuities in differential signaling is proposed. A known approach, using tightly coupled microstrips and providing CM reduction in the frequency range from DC till 6 GHz, is revisited and adapted to interconnect structures with a signal bandwidth (BW) up to 50 GHz. The design’s effectiveness
