书籍 ESD Protection in CMOS ICs
在互補式金氧半(CMOS)積體電路中，隨著量產製程的演進，元件的尺寸已縮減到深次微
米(deep-submicron)階段，以增進積體電路(IC)的性能及運算速度，以及降低每顆晶片的製造
成本。但隨著元件尺寸的縮減，卻出現一些可靠度的問題。
在次微米技術中，為了克服所謂熱載子(Hot-Carrier)問題而發展出 LDD(Lightly-Doped Drain)
製 ...
电源技术 DN378 低静态电流单片式降压型稳压器
 
Automobile electronic systems place high demands ontoday’s DC/DC converters. They must be able to preciselyregulate an output voltage in the face of wide temperatureand input voltage ranges—including load dump transientsin excess of 60V and cold crank voltage drops to 4V. Thec ...
电源技术 透过MOSFET电压电流最佳化控制传导性及辐射性EMI
經由改變外部閘極電阻(gate resistors)或增加一個跨在汲極(drain)和源極(source)的小電容來調整MOSFET的di/dt和dv/dt，去觀察它們如何對EMI產生影響。然後我們可了解到如何在效率和EMI之間取得平衡。我們拿一個有著單組輸出+12V/4.1A及初級側MOSFET AOTF11C60 (αMOSII/11A/600V/TO220F) 的50W電源轉接器(adapter)來做 ...
电源技术 电源芯片viper22a的工作原理
VIPER22A的内部结构可知,它与其它开关电源存在一些不同。开机后,300V的直流电压从DRAIN(漏极)脚进入集成电路,经整流和稳压后供给开关电源IC工作,从而使这个电路工作时不需要外接启动电阻。即使Vdd供电电路不正常,电源电路的振荡电路仍能起振,而且电路有输出电压。用这种专用电源IC的DVD机电源有故障时,故障现象和其他开 ...
无线通信 MAX7060的ASK_FSK的ISM射频发射机
Abstract: This application note illustrates the flexibility of the MAX7060 ASK/FSK transmitter. While the currently available evaluationkit (EV kit) has been optimized for the device's use in a specific frequency band (i.e., 288MHz to 390MHz), this document addresseshow the EV kit circuitry ca ...
单片机编程 PCA9544A 4channel I2C multiple
The PCA9544A provides 4 interrupt inputs, one for each channeland one open drain interrupt output. When an interrupt is generated byany device, it will be detected by the PCA9544A and the interruptoutput will be driven LOW. The channel need not be active fordetection of the interrupt. A bit is also ...
