Recently, the International Union of Pure and Applied Chemistry (IUPAC) announced the top ten emerging chemical technologies for 2024, and the triboelectric nanogenerator (TENG) technology invented by Academician Zhonglin Wang and his team from the Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences, was selected. The related research by Academician Wang’s team, titled … Read more
Click the Blue Text to Follow Us SUBSCRIBE to US WEI GAO/CALTECH Wearable devices, like almost all other technologies, require energy. Fortunately, energy is actually ubiquitous under the moderate power budget of wearable devices. It exists in sunlight and radio waves, sweat and body heat from the skin, and the movements and footsteps of a … Read more
Figure 3 PCB Wiring 4) Circuit Related Explanation As shown in Figure 1, R56 and R57 are the pull-up resistors on the I2C bus. The interrupt output and clock output of the PCF8563 are both open-drain outputs, so external pull-up resistors are also needed, such as R58 and R59 in Figure 1. If these two … Read more
There are often questions like this online,What should I learn after entering the IC industry to have better career prospects? What can I still learn now to further my studies in IC design? What skills will give me an advantage in interviews at major companies?In fact, learning low-power design is a great choice! Everyone has … Read more
The northwest wind is howling, and the annual heating season has arrived. Heating pipelines are so important during the winter in the north. The design of the pipelines is aimed at maximizing effective thermal energy under determined energy conditions. Low power design aims to meet functional requirements with minimal power consumption. The low power design … Read more
Today we analyze a classic microcontroller power supply circuit. The circuit schematic is shown below: ▲ Simplified Switch Circuit Before powering the circuit, the switch “TEST” is open, and the microcontroller is not powered through VCC. At this time, the base of T1 is grounded through R9 (100k), and is in the cutoff state. The … Read more

With the development of the times, people have gradually started to design various types of chips, one of which is the popular low-power chip design. These chips not only help extend the battery life of devices but also reduce the likelihood of overheating and improve system stability. If you want to design low-power chips, then … Read more
Source: Content from http://www.cnblogs.com/IClearner/, Author: IC_learner, thank you. Previously, we learned about the purpose of low power design and the composition of power consumption. Today, I will share some insights on power analysis. Since this learning is aimed at front-end design of digital ICs, the power analysis here is based on the power compiler tool … Read more
Source: Content fromhttp://www.cnblogs.com/IClearner/ , Author: IC_learner, Thank you. This section mainly introduces the use of gated clocks for low-power design. (4) Gated Clock The gated clock was briefly described in my first blog; here I will provide a more detailed description. We will mainly learn what gated clock circuits are, when to use gated clocks, … Read more
