LOW POWER CONTINUOUS TIME COMMON MODE SENSING FOR COMMON MODE FEEDBACK CIRCUITS
Journal of Circuits, Systems and Computers, 2010Continuous common mode feedback (CMFB) circuits having high input impedance and low distortion are proposed. The proposed circuits are characterized for 0.18 μm CMOS process with 1.8 V supply. Simulation results indicate that the proposed common mode detector consumes no standby power and CMFB circuit consumes 27–34% less power than previous high ...

A Three-Winding Common Mode Inductor
IEEE Transactions on Power Electronics, 2017Electronic products consist of parasitic capacitance between the circuit components and the ground, which introduces common mode (CM) noise. A CM inductor is used to block the noise following into the power supply affecting the others. However, the CM inductor and the parasitic capacitance could create resonance phenomenon that affect the filter ...

1968 IEEE Electromagnetic Compatibility Symposium Record, 1968
In this study of induction coupling between cables, the mutual inductance and capacitance between the wires of two cable circuits are resolved into common mode and normal mode parameters. All other relelvant parameters, and also the variables, are resolved in a similar manner.

Methodology for the Common Mode Analysis
SAE Technical Paper Series, 2007<div class="htmlview paragraph">The assumption usually made in the safety analysis of most systems is that the failure of any one component is independent of the failure of any other. If this assumption is not valid due to the system design and implementation, the estimated Fault Tree Analysis (FTA) event probabilities will be more optimistic ...

IEEE Transactions on Power Apparatus and Systems, 1975
Standard Reliability analysis techniques have demonstrated the capability to evaluate system vulnerability to random component failures. Recently, in the nuclear power industry, interest has been developing in methods to consider systematic, nonrandom, so-called "Common-mode" failures which are not tractable in quantitative terms using the usual fault ...

Common-mode rejection of the differential operational amplifier with shunt common-mode feedback
IEEE Journal of Solid-State Circuits, 1975A simple expression is derived for the common-mode rejection ratio (CMRR) of the differential operational amplifier with shunt common-mode (CM) feedback. The CMRR is exclusively expressed in terms of a fractional unbalance of the bridge circuit composed of an input resistor pair and a shunt CM feedback resistor pair.

EMC filter common mode resonance
2009 IEEE Bucharest PowerTech, 2009This paper discusses the possibility that high common mode voltages occur in low-voltage distribution due to oscillations between parallel connected EMC-filters. It is shown that such oscillations may occur in the frequency range between 2 kHz to 150 kHz.

Common-Mode Rejection Ratio-Two Definitions
IEEE Transactions on Biomedical Engineering, 1970Two different definitions of the common-mode rejection ratio for differential amplifiers are not clearly distinguished. These ratios may differ by orders of magnitude. When differential amplifiers are used to minimize common mode interference in bioelectric measurements, these two ratios should be carefully defined and their magnitudes determined ...

Common mode inductor material selection
Proceedings:Electrical Electronics Insulation Conference and Electrical Manufacturing & Coil Winding Conference, 2002As government agencies continue to tighten the requirements for electromagnetic compatibility, design engineers are forced to pay closer attention to the emissions created by their products. This is particularly true for DC-DC converters. Their high switching frequencies and steep pulse slopes are an excellent breeding ground for EMI.

Occurrence of common mode failure
Reliability Engineering & System Safety, 1994Abstract In technical facilities, for example in nuclear power plants, redundant systems are used to prevent random failures from deleting the complete system function. However, although this redundancy concept is adequate to cope with random failures in single redundancies, its applicability is limited in case of multiple failures due to a ...
