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
The report from Electronic Enthusiasts Network (by Liang Haobin) states that as optical modules develop towards 800G and 1.6T high speeds, DSP is facing increasing challenges, including performance and power consumption. Due to the small size of optical modules and the difficulty in heat dissipation, the power consumption of high-performance DSPs determines whether stable operation … Read more
—Knowing and doing are the farthest distances in the world. In previous articles, we introduced the aspects that need to be considered in the front-end architecture and design of SoC, and provided some reference solutions. The last article described the relevant content of UPF, completing the overall plan and UPF. The next step is the … Read more
In industrial and consumer electronics, an increasing number of devices require battery power. To enable devices to operate longer with limited battery capacity, we need to master low power design techniques for microcontrollers. This article will introduce several commonly used methods to reduce power consumption based on practical applications. 1. Understanding Power Consumption Power consumption … Read more
