1>.Operational Amplifiers:different from the resistor,the inductor and the capacitor,it's a multi-terminal element,also an active and intergrated device,it has two function,operation and amplification. 2>.OP package type: DIP package,SOP package,and…

排版有点乱.... ========================================================================= Operational Amplifiers (OAs) are highly stable, high gain dc difference amplifiers. Sincethere is no capacitive coupling between their various amplifying stages, they…

RFID读写器的工作原理 RFID的数据采集以读写器为主导,RFID读写器是一种通过无线通信,实现对标签识别和内存数据的读出和写入操作的装置. 读写器又称为阅读器或读头(Reader).查询器(Interrogator).读出装置(Reading Device). 扫描器(Scanner).通信器(Communicator).编程/编码器(Programmer)等等. 读写器工作原理 RFID读写器的基本原理是利用射频信号与空间耦合传输特性,使电子标签与阅读器的耦合元件在射频耦合通道内进行能量传…

DC-DC Controllers Use Average-Current-Mode Control for Infotainment Applications Abstract: Auto infotainment products (multimedia and telematics) are demanding more power and challenging a vehicle's power-management systems. This application note exp…

LDO current regulator for power LED Challenge You've got a power LED? Great! Build a flash light! What does the spec say? "Voltage: 3.6 .. 3.8 V, power 3 W." Okay. This means that it draws some 800 mA. Three mignon cells give 4.5 V for at least…

转载的:   说来惭愧,我所了解的牛人也只是大学教授,工业界的高手了解的还太少,虽然我对教育界的牛人了解的也不多,但这里也要牢骚几句,论坛上的人好像只是认识Gray,Razavi,Allen,Lee,要不是THU用Sansen的书估计大家还不知道有sansen这号人吧,其实不要只盯着Berkley,Stanford,UCLA,大家也应该了解一下KU Leuven这样的欧洲名校,了解一下和Razavi同时期的M.Steyaert.废话就不多说了,先要介绍一下我选的牛人,主要是依据ISSCC50周年…

The general approach using DDAs will be to simulate a system of first-order differential equations, which can be nonlinear. Analog computers use operational amplifiers to do mathematical integration. We will use digital summers and registers. For any…

如何在Python中加速信号处理 This post is the eighth installment of the series of articles on the RAPIDS ecosystem. The series explores and discusses various aspects of RAPIDS that allow its users solve ETL (Extract, Transform, Load) problems, build ML (Machine…

Transimpedance amplifiers (TIAs) act as front-end amplifiers for optical sensors such as photodiodes, converting the sensor’s output current to a voltage. TIAs are conceptually simple: a feedback resistor (RF) across an operational amplifier (op amp)…
