In January of this year, most regions in China experienced severe cold weather. Some jokingly said they could run benchmarks on their phones to keep warm, reflecting a deeply rooted issue in people’s minds regarding phone heat generation. As the core of the mobile phone, the CPU largely represents the phone’s performance. From the initial … Read more
With the development of technology, smart home devices have gradually entered thousands of households. But many people may ask: do these devices really help us save electricity? This article will analyze the impact of smart home devices on electricity bills from the perspective of a professional electrician and provide practical optimization strategies. 01 Analysis of … Read more
Click the blue WeChat name below the title to quickly follow With the continuous development of process nodes (now commonly at 28nm, 22nm, 16nm, 14nm, and even some at 7nm), the performance demands of chips are increasing, and their scale is growing larger. Digital IC design engineers are becoming increasingly concerned about chip power consumption, … Read more
After years of low-power hardware design (the hardware and software design in the company are separate, and I have always been doing hardware. Facing low-power production issues in hardware can often be quite challenging), I found that one common issue is that the IO is not configured properly before the microcontroller enters sleep mode. The … Read more
Looking at today’s applications, whether in the Internet of Things, consumer mobile devices, or various devices that can connect to wall outlets, including servers, low power consumption has become a differentiating factor and a necessary condition for product success (as noted by techsugar). Written by: Brian Bailey Translated by: Editorial Team Advancements in mobile technology … Read more
In the early stages of IC design, the main parameters of concern were performance (timing) and area. EDA tools minimized area while meeting performance requirements. At this time, power consumption was not a major concern. Because CMOS technology exhibits relatively low power consumption at lower clock frequencies, leakage current can be negligible. However, as transistor … Read more

This article mainly introduces how to reduce power consumption at various levels of chip design. 1 Introduction In chip design, we often mention the PPA trade-off, which stands for Power, Performance, and Area. … Read more
AuthorGuilin Zhong: (WeChat ID: great_baskerball) Editor of Smart Product Circle In 2015, the monthly shipment of WiFi chips used in the Internet of Things (IoT) reached 3-4 million units, and it is expected to surpass 100 million units in 2016. What are the reasons behind this surge? How has it evolved? With the continuous stimulation … Read more
The low power consumption of ZigBee is something everyone is very concerned about, for example, devices powered by button batteries. (Currently, I have tested that PM2 is about 1.2uA and PM3 is around 0.3uA for the core board, not counting peripherals.) Today, I will just jot down a simple memo: 1. Network Joining Power Consumption … Read more
Click the blue words above to follow us Dynamic Power Management (DPM) is a technology that dynamically adjusts power states based on real-time information during system operation, aimed at optimizing the balance between power consumption and performance. This technology is particularly suitable for portable, mobile, and handheld electronic devices that rely on battery power, extending … Read more
