Learning the MIPI C-PHY Standard: A Universal Multi-Signal Transmission Solution

Learning the MIPI C-PHY Standard: A Universal Multi-Signal Transmission Solution

Traditional synchronous digital communication buses rely on two fundamental principles related to signal modulation and maximum likelihood sampling. In short, digital information transmission begins with representing information using data bits, which are then encoded into physical quantities such as voltage potentials or electronic currents. These physical quantities are transmitted through physical media such as metal … Read more

Why Chips Need Low Dielectric Constant (Low-k) Materials

Why Chips Need Low Dielectric Constant (Low-k) Materials

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
