[i] I made a simplex wireless transmitter, using AD9851, DDS frequency synthesis chip. The output modulation wave has a sine wave from nowhere, with a frequency of about 600KHz. The frequency of the w...
I have been studying hardware for more than half a year, but I feel like I have no idea what I am doing. From the 51 single-chip microcomputer to the FPGA, I feel like I don't know more and more, and ...
[align=left][color=#000]Welcome back to the DC/DC converter datasheet series. [url=https://bbs.eeworld.com.cn/thread-491041-1-1.html]Given the introduction to system efficiency in the previous article...
Our company is testing LDO products, but during the test process, the output voltage of some batches is higher than the standard voltage regulation value, resulting in a low yield; I would like to ask...
Can the Zigbee coordinator specify how many routers or terminals to add? For example, if the maximum number of sub-devices is 30, can it specify that a maximum of 10 routers and 20 terminals be added?...
Chinese translation result: The Chinese translation result is not very good, only part of it is translated. Many TI things are still in English, and some translations are not very accurate. Code Compo...
At present, the development of wireless power supply technology for electric vehicles (EVs) is becoming more and more active. In 2012, Volvo of Sweden established Volvo Technology Japan in Tokyo as...[Details]

Two simple circuits are implemented to drive two LEDs from a battery powered microprocessor.
This design is based on a circuit that uses three resistors and a microprocessor I/O pin as an input h...[Details]
Although it is relatively easy to check the stability of a simple amplifier at lower frequencies, it may be much more difficult to evaluate the stability of a more complex circuit. This artic...[Details]
We know that microcontroller development tools generally include real-time online emulators and programmers. Among them, online emulators are very good tools, but they are also more expensive...[Details]
Microcalorimetry
is used to determine energy relationships. Microcalorimetry techniques are often required when performing calorimetric experiments with small sample sizes or slow heating rat...[Details]
Only a small number of LED manufacturers can produce high-quality LEDs. For applications that are only used for simple indication, low-quality LEDs are sufficient. However, high-quality LEDs must...[Details]
