A novel common-mode filter (CMF) design based on signal interference technique
2014 IEEE Electrical Design of Advanced Packaging & Systems Symposium (EDAPS), 2014The signal interference technique is firstly employed to design the common-mode filter (CMF) for differential digital circuit applications. Using the network analysis, design curves for three common-mode transmission zeros are available by simple steps. A test sample is realized in two-layer PCB. The fractional bandwidth of common-mode suppression band

Transmission line modelling exploiting 'common-mode' signals
2007Digital Subscriber Line (DSL) technology provides broadband service over 'twisted pair' copper wires of the existing telephone network. The inherent structure of this network causes crosstalk, which significantly reduces the achievable bit rate for each user.

Experimental verification of signal integrity deterioration due to package-common-mode resonance
International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2012When an LSI package is mounted on a PCB, parasitic couplings are unintentionally generated between them. Antiresonance of these couplings (package-common-mode resonance) can cause degradation of signal and power integrity. In this paper, the authors experimentally verified the package-common-mode resonance by comparing scattering parameters with ...

Cancellation of common mode currents due to differential or counter-directed signals
IEEE International Symposium on Electromagnetic Compatibility, 2003In the design of high speed printed circuit boards (PCBs), differential signals are preferred to distribute clock signals across the board. Differential signals are highly resistant to other signals or external fields, and do not cause strong radiation levels, due to the field cancellation resulting from the signal's opposite polarity, Differential ...

Common-Mode Interference Reduction in Seismic Recording Using a Programmable Signal Processor
IETE Technical Review, 1986Contamination of seismic signals by common-mode pick-ups induced into geo phone cables lead to significant loss of information. Current methods to reduce this use notch filters. Earlier, manual balancing of lines was resorted to. Whereas notch filtering suppresses the fundamental induced frequency, it leaves the harmonics unaffected.

Reduction of Common-Mode and Differential-Mode Noises Using Timing-Offset Differential Signal
IEEE Transactions on Components, Packaging and Manufacturing Technology, 2015In this paper, the timing-offset differential signal is proposed to reduce the common-mode and differential-mode noises induced by the right-angled differential transmission line. The right-angled differential transmission line using the timing-offset differential signal can greatly reduce the time-domain transmission common-mode noise from 0.065 to 0 ...

Four-port microwave networks with intrinsic broad-band suppression of common-mode signals
IEEE Transactions on Microwave Theory and Techniques, 2005Two classes of four-port microwave networks are defined with discriminative even- and odd-mode transmission characteristics. Design of the networks is based on filter prototypes with predefined sets of transmission zeros and, consequently, a desired response can be synthesized.

Common-mode suppression design for gigahertz differential signals based on coupled C-slotlines
2015 Asia-Pacific Microwave Conference (APMC), 2015For wideband common-mode noise suppression in high-speed differential signals, a low-cost compact filter is proposed and designed by etching two coupled C-slotlines on the ground plane. It is found that the bandwidth of the common-mode stopband over −10dB is from 2.4GHz to 6.35GHz with no degradation of the differential-mode insertion loss and group ...
