模拟电子 高集成数字RF调制器解决方案
Abstract: A digital RF modulator, an integrated solution that satisfies stringent DOCSIS RF-performancerequirements, takes advantage of modern technologies like high-performance wideband digital-to-analogconversion and CMOS technology scaling. This application note describes the concept and advant ...
模拟电子 小面积和大面积光电二极管的低噪声放大器
 
Photodiodes can be broken into two categories: largearea photodiodes with their attendant high capacitance(30pF to 3000pF) and smaller area photodiodes withrelatively low capacitance (10pF or less). For optimalsignal-to-noise performance, a transimpedance amplifi erconsisting of an invert ...
电源技术 高效LCD液晶照明技术
In August of 1992 LTC published Application Note 49,
“Illumination Circuitry for Liquid Crystal Displays.” One
notable aspect of this event is that it generated more
response than all previous LTC application notes combined.
This level of interest, along with significant performanc ...
测试测量 产品检测中裕度和校准的乐趣
Abstract: This application note presents an overview of electronic margining and its value in detectingpotential system failures before a product ships from the factory. It is a calibration method that effectivelypredicts and allows adjustments to improve product quality. Margining also can be use ...

The PCI Local bus concept was developed to break
the PC data I/O bottleneck and clearly opens the door
to increasing system speed and expansion capabilities.
The PCI Local bus moves high speed peripherals
from the I/O bus and places them closer to the system’s
processor bus, providing faster data t ...
