I recently encountered a difficult problem when repairing a company's circuit board. The 2596 circuit converted 24V to 5V, but the output was only a few volts, and the inductor became hot. The inducto...
[size=4]First of all, I would like to thank the moderator of dcexpert for giving me a copy of "Mastering Switching Power Supply Design Second Edition". I hope you will all be envious:loveliness:. [/si...
I would like to ask how to automatically add test points to the whole board in AD? The current method is rather clumsy. For example, for 20 networks, I first copy 20 test point pads, then add networks...
In order to prevent traffic accidents, when the intelligent detection device of the car detects danger ahead, it must send a warning message to the driver. The voice alarm clearly reminds the drive...[Details]
This article discusses how to use an ultra-low-power RF transceiver chip from Zarlink Semiconductor for pacemakers, neurostimulators, drug pumps, and other such implantable medical devices to achiev...[Details]
Embedded systems are the replacement products of computer technology, communication technology, semiconductor technology, microelectronics technology, voice and image data transmission technology, and...[Details]
Designers of hearing aids have stringent requirements. Hearing aids must be small enough to fit in or behind the ear, operate on ultra-low power, and be free of noise or distortion. To meet these requ...[Details]
JTAG Technology Introduction
One disadvantage of shrinking technology is that the complexity of testing small devices increases dramatically. When the board area is large, the board is tested...[Details]
Wireless personal area networks (or WPANs) are particularly useful for sensing, monitoring, and control applications. Cost-effective WPANs have the unique potential to implement wireless connectivi...[Details]
There are many ways to attenuate signals. The most commonly used method is to divide the voltage using resistors. The common circuits are as follows:
Oscilloscope pre-stage attenuation c...[Details]
introduction
In engineering practice, ultrasonic waves are often used to measure distances because of their strong directivity, slow energy consumption, and long propagation distance in th...[Details]
Introduction
Wireless operators are driving demand for broadband and data rates by offering enhanced data services to increase average revenue per user (ARPU). The need to provide users with ...[Details]
introduction
Traditional electric actuators are easy to use and save investment, and have been widely used in production process control systems in the fields of electricity, metallurgy, petro...[Details]
Anyone who has owned a laptop computer will have noticed that when running on battery power, their portable device behaves differently than when running on AC mains power—the display dims, the proc...[Details]
Capacitive sensing user interfaces are emerging as a practical and innovative alternative to mechanical buttons in mobile phones. While capacitive sensors can be viewed as a drop-in replacement fo...[Details]
Nowadays, the phenomenon of using cloned taxis and trucks for operation is becoming more and more serious. The so-called cloned car is one or several unlicensed vehicles that are used to copy anoth...[Details]
Novaled, a German company, has successfully developed p-type and n-type field effect transistors based on a single-layer pentacene semiconductor layer by using its own p-type and n-type dopants. This ...[Details]
When it comes to ATX power supply, people will think of two "classic" ICs: pulse width modulation chip TL494 and voltage comparator LM339. The new dedicated control chip AT2005B has the functions ...[Details]
