RF engineers should better understand applications outside their industry, because it is not your competitors that will disrupt you, but possibly AI. Imagine a day when a large AI model starts to excel in RF design, capable of simulating, debugging, and testing by itself… Then RF engineers will truly be overwhelmed; we can work 996, … Read more
Source: LightSense Technology Original Author: BENG This article briefly introduces several different types of chips. Different types of chips are accompanied by different node technologies. Except for logic chips, there is basically no need for technology smaller than 28nm. MEMS: Micro Electro Mechanical Systems (MEMS). Integrates industry-leading Complementary Metal-Oxide-Semiconductor (CMOS) and wafer stacking technology to … Read more
Source: Wisdom Microelectronics Original Author: Peng The reason chips are called chips is due to semiconductor technology; the biggest difference between chip systems and board-level systems is the use of semiconductor physical devices. Semiconductor devices are the foundation of chip companies. Even for chip companies or chip engineers, “semiconductor physics” is a daunting term. This … Read more
Compound semiconductors have excellent performance and a broad development prospect. Compound semiconductors mainly refer to second and third generation semiconductors such as Gallium Arsenide (GaAs), Gallium Nitride (GaN), and Silicon Carbide (SiC). Compared to the first generation of elemental semiconductors, they are significantly superior in high-frequency and high-temperature performance. Gallium Arsenide: It features high frequency, … Read more
Source: Wangcai Chip Original Author: Moshij What Is a Semiconductor? A semiconductor is a material with specific electrical properties that allows it to serve as the foundation for computers and other electronic devices. It is typically a solid chemical element or compound that conducts electricity under certain conditions but not under others. This makes it … Read more
Author Introduction Dr. Liu, Ph.D. from University of Electronic Science and Technology, an expert in microarchitecture. 1. Background The clock circuit is the most basic circuit in the chip. The performance of the clock circuit is related to whether all the modules in the SoC can achieve the expected goals, such as the main frequency … Read more
Overview In the design of high-speed analog signal chains, the layout and routing of the printed circuit board (PCB) need to consider many options, some of which are more important than others, while others depend on the application. The final answers vary, but in all cases, design engineers should consider the overall picture rather than … Read more
1、Passive Crystals——Passive crystals require an oscillator within the DSP chip, with recommended connection methods provided in the datasheet. Passive crystals do not have voltage issues; the signal level is variable, meaning it is determined by the oscillation circuit. The same crystal can be used for various voltage requirements, making it suitable for DSPs with different … Read more
