Hello everyone, I am Goat. Continuing with some other signal quality issues related to I2C. If you encounter these problems, how can you resolve them? Back Reflection Back reflection poses significant risks to clock-type signals, and since the I2C CLK signal is a clock-type signal, the presence of back reflection can lead to sampling errors. … Read more
In the previous issue, we introduced some background knowledge about chip packaging:A Beginner’s Guide to Chip PackagingIn this issue, we will focus on the specific process of packaging.As previously mentioned, there are many forms of packaging, including traditional and advanced packaging.Different packaging types have different processes and techniques. After completing the entire write-up, I found … Read more
In modern chips, billions of transistors are interconnected by metal lines to form complex circuits. As the manufacturing process enters the nanoscale, a seemingly “invisible” problem gradually comes to light:Capacitive coupling between metal lines. This coupling not only slows down signal transmission speeds but can also lead to data transmission errors. The key to solving … Read more
In a middle school eighth-grade Chinese textbook, there is an article about Wang Shuyuan, a craftsman from Jiangnan during the Ming Dynasty, who carved a painting of Su Dongpo’s night tour of Chibi on a jujube pit. The eight carved windows can be opened and closed, with inscriptions on the window frames reading “The mountain … Read more
