At present, with the continuous development of modern medical devices, especially electronic instruments directly connected to the human body, in addition to the increasingly high...[Details]
For more than 10 years, analog-to-digital converters (ADCs) have been widely used in industrial process control, medical instruments, communication systems, radar and other products as a booster of in...[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]
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]
TD-SCDMA terminal conformance test includes three types of tests: RF index test (reference standard: 3GPPTS34.122), protocol signaling test (reference standard: 3GPPTS34.123) and other tests (refer...[Details]
Signal sources have developed to a very wide range today. We can classify them according to the frequency range: ultra-low frequency (0.1m~1kHz), audio (20Hz~20kHz), video (20kHz~10MHz), radio fre...[Details]
In electronic measurement technology, frequency measurement is one of the most basic measurements. The commonly used frequency measurement method and period measurement method have great limitation...[Details]
introduction
Taking care of babies is very tiring because they wake up and sleep frequently, and activities such as feeding and changing clothes will take up a lot of adults' time and energy. ...[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]
Preface
In the analog era, due to the unchanged specifications and relatively simple device connections, as well as users' low requirements for image quality, the relatively simple environment...[Details]
In a Class D audio power amplifier, the preamplifier is a relatively important module. It is located at the front of the entire topology and completes the processing of the input signal source,...[Details]
A correct circuit design cannot be manufactured 100% correctly when it is taken to the factory for manufacturing. It will always be affected by various uncertainties, such as deviations in manufact...[Details]
