According to reports from Electronic Enthusiasts (by Huang Shanming), the smart toy market has grown rapidly in recent years, with features such as voice recognition and image interaction becoming key competitive elements. However, high chip costs and development difficulties have made it challenging for many developers to advance their projects. How can we find suitable … Read more
After years of low-power hardware design (the hardware and software design in the company are separate, and I have always worked on hardware, often facing the challenges of low-power production incidents), one common issue is that the IO configuration is not set correctly before the microcontroller enters sleep mode. The main problems with the product … Read more
1 Small External Buses such as Microcontrollers Microcontrollers (MCUs) generally have external buses that can be used to connect true color LCDs (asynchronous bus interface TFT displays). Most mobile phones use synchronous interfaces (first providing an address, then continuously sending data). 2 Application Scenarios of ARM Processors ARM7: Industrial control, mobile phones; ARM9: Image display; … Read more
Question: What are the differences between the WiFi 6+ technology mentioned in the promotional materials for Huawei WiFi 6 routers AX3 and AX3 Pro and regular WiFi 6? Answer: Based on the current client hardware situation, there is no noticeable difference in user experience. Huawei WiFi 6+ or Intel WiFi 6 Gig+ essentially both belong … Read more

With the increase in device density and clock frequency of chips under advanced processes, power consumption has also significantly increased. At the same time, the supply voltage and transistor threshold voltage have been reduced, leading to significant leakage current. High power consumption can cause excessive temperature during device operation, reducing reliability due to electromigration and … Read more
This article was originally published in the Zhihu column [The Path of Digital IC Backend Engineers]. Multi-bit cells have been widely used in numerous chip designs as a means to control power consumption, and various EDA tools provide extensive and comprehensive support for them. Today, we will start with the basic structure and principles of … Read more
Low Power Design Methods – Frequency and Voltage Scaling The practical operational space of circuit design lies in the process, design goals, process libraries, and timing analysis methods. Under special processes, temperature inversion particularly limits the range of timing, voltage, and temperature to maintain their normal monotonic relationship. A detailed analysis of all these factors … Read more
The manufacturing process of chips has been continuously evolving, and today, this digit measured in nanometers has entered the single-digit era. While this “shrinkage” at one end has triggered an “increase” at the other end, namely the integration level and the increasingly complex power consumption schemes and power supply systems, the testing costs of chips … Read more
