For an undamped system, a spring connects a car with a certain mass and a wall. What will happen if a certain amount of energy is given to the car? The car will continue to oscillate. Imagine that the...
UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]
The U.S. Food and Drug Administration (FDA) points out that home health care is the fastest growing area in the medical device industry. Driven by the increase in average life expectancy, the increasi...[Details]
Magnetic resonance imaging (MRI) systems can take high-resolution cross-sectional perspective images of the human body, providing very useful information for medical diagnosis. The radio frequency pro...[Details]
Ultrasound systems are among the most sophisticated and complex signal processing instruments in widespread use today. Like any complex instrument, there are many trade-offs to be made in implement...[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]
The role of digital-to-analog converters
Real-world analog signals, such as temperature, pressure, sound, or images, are constantly being converted into digital form that is easier to store, p...[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]
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]
Many MEMS devices, such as accelerometers and mechanical resonance devices, require a vacuum environment to realize their designed functions. However, verifying whether the package cavity has reach...[Details]
To help improve DC/DC conversion efficiency at lighter loads and higher frequencies, Schottky diodes can be integrated into MOSFET chips to form a single package to reduce power dissipation in the ...[Details]
