Construction Strategy of ESD Protection CircuitAbstract： The principles used to construct ESD protection on circuits and the basic conceptions of ESD protection design are presented.Key words：ESD protection/On circuit, ESD design window, ESD current path1 引言静电放电（ESD，Electrostatic Discharge）给电子器件环境会带来破坏性的后果。它是造成集成电路失效的主要原因之一。随着集成电路工艺不断发展，互补金属氧化物半导体（CMOS，Complementary Metal-Oxide Semiconductor）的特征尺寸不断缩小，金属氧化物半导体(MOS, Metal-Oxide Semiconductor)的栅氧厚度越来越薄，MOS 管能承受的电流和电压也越来越小，因此要进一步优化电路的抗ESD 性能，需要从全芯片ESD 保护结构的设计来进行考虑。

基于USB接口的数据采集模块的设计与实现Design and Implementation of USB-Based Data Acquisition Module路 永 伸(天津科技大学电子信息与自动化学院，天津300222)摘要文中给出基于USB接口的数据采集模块的设计与实现。硬件设计采用以Adpc831与PDIUSBDI2为主的器件进行硬件设计，采用Windriver开发USB驱动，并用Visual C十十6.0对主机软件中硬件接口操作部分进行动态链接库封装。关键词USB 数据采集Adpc831 PDNSBDI2 Windriver动态链接库Abstract T hed esigna ndim plementaitono fU SB-BasedD ataA cquisiitonM oduleis g iven.Th ec hips oluitonm ainlyw ithA dpc831a ndP DTUSBD12i sused for hardware design.

mp3设计程序资料，采用c语言编写。 README file for yampp-3 source code 2001-05-27 This is the current state of the yampp-3 source code, 2001-05-27. This code is intended to run on Rev. B of the yampp-3 PCB, but can ofcourse be used on compatible systems as well. It still uses the "old" song selection system as the yampp-2. However, the disk handling routines has improved a lot and the obviosly, the new VS1001 handling has been put in. The codesize is almost at it s maximum at 1F40 bytes. A .ROM file is included if you don t have the compiler set up. For now, the documentation is in the code

数字运算，判断一个数是否接近素数 A Niven number is a number such that the sum of its digits divides itself. For example, 111 is a Niven number because the sum of its digits is 3, which divides 111. We can also specify a number in another base b, and a number in base b is a Niven number if the sum of its digits divides its value. Given b (2 <= b <= 10) and a number in base b, determine whether it is a Niven number or not. Input Each line of input contains the base b, followed by a string of digits representing a positive integer in that base. There are no leading zeroes. The input is terminated by a line consisting of 0 alone. Output For each case, print "yes" on a line if the given number is a Niven number, and "no" otherwise. Sample Input 10 111 2 110 10 123 6 1000 8 2314 0 Sample Output yes yes no yes no

The Hopfield model is a distributed model of an associative memory. Neurons are pixels and can take the values of -1 (off) or +1 (on). The network has stored a certain number of pixel patterns. During a retrieval phase, the network is started with some initial configuration and the network dynamics evolves towards the stored pattern which is closest to the initial configuration.
