模拟电子 了解模数转换器的噪声、ENOB
Abstract: Specifications such as noise, effective number of bits (ENOB), effective resolution, and noise-free resolution inlarge part define how accurate an ADC really is. Consequently, understanding the performance metrics related to noise isone of the most difficult aspects of transitioning from ...
模拟电子 视频差分放大器带来低电压应用的多功能性
 
The LT®6552 is a specialized dual-differencing 75MHzoperational amplifier ideal for rejecting common modenoise as a video line receiver. The input pairs are designedto operate with equal but opposite large-signal differencesand provide exceptional high frequency commonmode rejection ( ...
电源技术 电源工程师-电路设计中的英雄
Abstract: We don't expect manufacturers to produce clothes that in one size that fits everyone. In thesame way, one ESD component can't solve all issues—each application has different ESD requirements.Knowing that "one size fits all" cannot apply to power design, the power designer, ...
电源技术 电源调整与虚拟地
Abstract: Rail splitting is creating an artificial virtual ground as a reference voltage. It is used to set the signalto match the op amp's "sweet spot." An op amp has the most linear- and distortion-free qualities at that sweetspot. Typically, the sweet spot occurs near the center between the ...
电源技术 超低功率转换器的控制方案消除开关噪声
 
An essential component of a noise-free audio device isa clean power supply, but few switching regulators canoperate at high efficiency while keeping the switchingfrequency out of the audio band. The LTC®3620 fills thisvoid. It is a high efficiency 15mA buck regulator with aprogrammabl ...
电源技术 高电压,低噪音,DCDC转换器
 
Photomultipliers (PMT), avalanche photodiodes (APD),ultrasonic transducers, capacitance microphones, radiationdetectors and similar devices require high voltage,low current bias. Additionally, the high voltage must bepristinely free of noise; well under a millivolt is a commonrequirement ...

无线通信 Heart-RateFitness Monitors Go Wireless
Abstract: This article explains the recent trend in heart-rate and fitness monitors to go wireless toeliminate cables to allow free movement, and allow convenient data collection without the need to plug intheir devices. It details a typical wireless system, using the MAX1472 crystal-referenced ph ...
