Introduction to the design method of non-isolated buck power supply Non-isolated buck power supply is a commonly used power supply structure, accounting for more than 90% of fluorescent lamp power sup...
Designers implement current sensing for system protection and monitoring by placing a very small "shunt" resistor in series with the load and a current sense amplifier or op amp between the two. While...
Hello everyone, I would like to ask you how to implement the status prompt under evc, for example, when I am uploading a file, there will be a window prompting that it is uploading, and when the trans...
Use the IO of the microcontroller to control the switch (positive pole of the power supply) of a 3v-5v boost board. The characteristics of the GPG8 port of the microcontroller are: shutdown (with batt...
My LCD refresh rate is normal at 30MHZ, but it flickers a little. When it is increased to 60MHZ, the screen drifts and the coordinates are incorrect....
1 Overview
Drugs are like a "double-edged sword". They can treat diseases but can also cause serious adverse consequences. The dual nature of drugs depends on whether they are used rationally....[Details]
Radio Frequency Identification (RFID) technology is a non-contact automatic identification technology that uses wireless radio frequency communication. Compared with the currently widely used barco...[Details]
In some applications, such as data loggers, it is desirable to have multiplexed analog outputs. When only a single output is active at a time, a voltage-output DAC">digital-to-analog converter (DAC) a...[Details]
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]
Pulse oximeters, non-invasive instruments used to monitor a patient's blood oxygen saturation, are benefiting from moving away from expensive discrete component solutions toward more integrated design...[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]
1 Overview
The BP01 pressure sensor is specially designed for monitoring blood pressure and is mainly used in portable electronic sphygmomanometers. It uses a precision thick-film ceramic chip and...[Details]
As the application scope of medical equipment expands from hospitals to emergency response and home medical environments, its mobility will be determined by many factors. In addition, medical equip...[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]
Today's mobile phone production testing faces an increasingly complex environment, with challenges of multiple frequency bands and multiple standards, pressure on production test speed, and pressur...[Details]
Abstract: Based on the research of the communication process between the reader and the RFID tag, combined with the EPC C1G2 protocol and ISO/IEC18000.6 protocol, a digital circuit of RFID tag appl...[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]
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]
