First question - I am studying computer science, but I am interested in hardware. I just saw a brother in an old post saying that learning VHDL language has no future. I am currently learning it, coul...
I use Guangzhou Friendly Arm's QQ2440V3, and use ActiveSync to download the program. I can see the mobile device item and the folder in wince through the My Computer page of the PC, which means that t...
I use LM2776 to generate -5V voltage. The problem now is that after power on, the output voltage of the place where -5V should be output is 0.67V; but after touching the -5 output pin with an oscillos...
During normal operation, motors and actuators may experience overcurrent and overheating damage due to electrical shorts or circuit overloads. Both intermittent and continuous operation motors can ben...
Until now, designers have faced a trade-off in ADC selection. Pipeline converters offer high resolution and wide dynamic range, but their power consumption is quite high. The alternative, discrete ...[Details]
No other sector is feeling the pressure for change more acutely than the healthcare industry. Healthcare organizations and services are desperate to reduce costs, but the challenge is to do so without...[Details]
Ultrasonic tooth cleaning machines have been widely used in the medical field. Most ultrasonic tooth cleaning machines used at home and abroad now use analog oscillation circuits. There are the follow...[Details]
Blood pressure is one of the important physiological parameters of the human body. Accurate measurement of it is conducive to early detection and identification of hypertension types, and to the pro...[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]
Keeping the heart environment compact and warm is beneficial in most cases, but it’s another story for electronic heart scanners. When GE Healthcare was designing a scanner that was said to be the fas...[Details]
Controller Area Network (CAN) is a type of fieldbus. It is a serial communication network that effectively supports distributed control or real-time control and is recognized as one of the most pro...[Details]
As a single-host multi-slave bus system, the number of slave devices that can be connected to a 1-Wire bus is almost unlimited. In order to avoid logical conflicts, the 1-Wire bus interfaces of all...[Details]
As the price of readers and tags decreases and the global market expands, the application of radio frequency identification (RFID) is increasing day by day. Tags can be powered by readers (passive ...[Details]
Due to the needs of medical development, in many cases, general thermometers can no longer meet the requirements of fast and accurate temperature measurement, such as measuring human body temperature ...[Details]

With the rapid development of my country's aviation industry, various new aircraft and control equipment have been successfully developed. Some previous measurement and control eq...[Details]
Lithium-ion batteries have a high energy-to-weight and energy-to-volume ratio, no memory effect, can be recharged many times, have a long service life, and are becoming increasingly cheaper. A good...[Details]
Preface
Phase-modulated pulse signals can achieve a large compression ratio. As a commonly used pulse compression signal, they are widely used in modern radar and communication systems. Wi...[Details]
Complex circuits and 3D EM simulation tools have reached a point where complex system-level behavior can be simulated before fabrication. Performing EM simulations simultaneously with circuit simul...[Details]
