Characteristic impedance of the transmission line

Posted on July 16, 2018 by G

From a battery point of view, once the design engineer connects the battery leads to the front end of the transmission line, there is always a constant value of current flowing out of the battery and keeping the voltage signal constant. Some people may ask, what kind of electronic components have such behavior? A constant current value is maintained when a constant voltage signal is added, of course the resistance.

Method for solving signal integrity problems in ASIC chip design

Posted on July 12, 2018 by G

For the design of ASIC (Application Specific Integrated Circuit), the performance of standard cells is wasted due to the application of standard cells, shorter development cycle, and more relaxed protection between cells. Therefore, the key to high-end ASIC chip design is to ensure high-performance chips are delivered with shorter development time.

Focus on signal integrity in complex designs

Posted on July 12, 2018 by G

In SoC design, the coupling between signals can cause signal integrity problems. Neglecting signal integrity problems can lead to crosstalk between signals, and reliability, manufacturability and system performance will also be reduced.

EMC design skills inside the product

Posted on July 10, 2018 by G

At present, electronic equipment is used in various electronic devices and systems, and printed circuit boards are still the main assembly method. Practice has proved that even if the schematic design of the circuit is correct and the printed circuit board is not properly designed, it will adversely affect the reliability of the electronic device. For example, if the two thin parallel lines of the printed board are in close proximity, a delay in the signal waveform is formed, and reflected noise is formed at the end of the transmission line. Therefore, when designing a printed circuit board, care should be taken to use the correct method.

The importance of layout in high speed PCB design

Posted on July 10, 2018 by G

Throughout the successful electronic products, we must have five characteristics: one is stable in performance; two is beautiful in appearance; three is easy to apply; four is reasonable in cost; five is convenient for mass production; and it is not a successful product. These five points are related to the layout. In other words, a good and reasonable layout is to fully consider the above five points, so the layout is a very important part of the success of the product.

Electromagnetic compatibility design

Posted on July 04, 2018 by G

Electromagnetic compatibility refers to the ability of an electronic device to work in a coordinated and efficient manner in various electromagnetic environments. The purpose of the electromagnetic compatibility design is to enable the electronic device to suppress various external interferences, enable the electronic device to work normally in a specific electromagnetic environment, and at the same time reduce the electromagnetic interference of the electronic device itself to other electronic devices.

At present, electronic equipment is still used in printed circuit boards as the main assembly method for various electronic devices and systems. Practice has proved that even if the circuit schematic design is correct, improper design of the printed circuit board will also have an adverse effect on the reliability of electronic equipment. For example, if the two fine parallel lines of the printed board are in close proximity, a delay in the signal waveform is formed, and reflection noise is formed at the end of the transmission line. Therefore, when designing a printed circuit board, it should be noted that the correct method is used.

Seven Considerations in PCB Design

Posted on June 08, 2018 by G

The schematic design before single-panel proofing is a preliminary preparation work. When drawing a schematic diagram, it is necessary to pay attention to the final connection of each file as a whole in the hierarchical design. This also has important significance for the future work. Due to software differences, some software may appear to be physically connected (electrically). If you do not use related detection tools to detect, if something goes wrong, it will be too late to wait until the board is ready. Therefore, it is important to emphasize the importance of doing it in order, and we hope to draw everyone’s attention.

The core of PCB design and solutions

Posted on June 08, 2018 by G

The design of a printed circuit board (PCB) refers to the layout of the circuit through the design principle drawing to produce the circuit board at the lowest possible cost. In the past, this usually required expensive specialized tools to complete, but now, with the increasing popularity of free high-performance software tools, such as DesignSparkPCB, and design models, circuit board designers have greatly accelerated the design speed.
