Problems solved by technology

Disadvantageously, in many cases the reference plane is noisy, so that the noise finds its way from the noisy reference plane to the signal line through the bypass capacitor
In other words, these bypass capacitors may introduce more noise into the signal line than was originally the case

Embodiment Construction

[0018] Reference will now be made in detail to presently preferred structures or embodiments and methods of the invention, which constitute the best modes of carrying out the invention currently known to the inventors.

[0019] In an embodiment of the invention, an electronic module set with reduced EMI noise emissions is presented. according to figure 1 , shows a schematic diagram of the electronic module set of the present invention. The electronic module set 10 includes an electronic module assembly 12 that emits EMI noise. Typically, component 12 will be located on carrier 14, which is a circuit board. Group 10 also has a first electrical reference area 16 in communication with electronic assembly 12 . As used herein, maintaining contact means maintaining electrical contact, although such electrical contact may have one or more additional intervening electronic components. The first electrical reference zone 16 is characterized by a first electromagnetic noise signal t...

Abstract

The present invention provides an electronic module assembly with reduced EMI noise emission. The electronic module assembly of the invention includes an electronic module component that emits EMI noise. The electronic module assembly has a first electric reference region and a second electric reference region that is in communication with electronic module component. An impedance component is positioned in series with the first reference region and the second reference region such that impedance component attenuates the first electromagnetic noise signal. The electronic module assembly further includes low pass filter component that is in electrical communication with electronic module component. The present invention also provides a method of reducing EMI noise emission.

Description

technical field [0001] The present invention relates to a device and method for reducing electromagnetic noise on the input and output of electronic components; more particularly, to a method for reducing the input and output of electronic components contained in automobiles. Apparatus and methods for electromagnetic noise on terminals. Background technique [0002] The inclusion of electronic components in motor vehicles has followed the trajectory of development and improvement of such devices. Since the development of the first automobile, there has been a trend to replace mechanical devices with electronic devices capable of operating in more sophisticated ways. Examples of such equipment include braking systems, engine control microprocessors, and the like. In addition, new technologies have been integrated with automotive vehicles as such technology has become available. Examples of such technologies include entertainment systems (radio, CD players), communication s...
