  1. In this paper, they are set forth at first that the kinds of computer - simulation of electronic devices, the development and the requirements of mosfet ' s model and the way of gain the models " parameters, the dc models have been bui it in chapter 2 and the models of big signals have been deduced in chapter 3, they are different from the equivalent circuit models in the traditional software pspice that they come from the numer i ca i - s i mu i at i on wh i ch is based on the essence equat i on, so the precision of simulation is enhanced ? mosfet ' s small signal models of low frequency, intermediate frequency and high frequency have been built in chapter 4 and chapter 5, although the equivalent circuit models in pspice are used for reference to bui id them, they have their own characteristics which are analyzed at a i i kinds of situations, so that the simulation software for mosfet can be written according them and it i s a i so benef i c i a i for us to catch the gen i us character i st i cs of mosfet and to d esign all kinds of applicable devices the correctness of the models is simply proved in chapter 6

    本文首先介紹了電子件計算機模擬的分類、 mosfet的建模發展動態、對件模型的要求以及模型參數的提方法。在第二章中建立了mos晶體管在流端電壓條件下的工作模型;第三章推導了mosfet的大信號模型,這兩類模型不同於傳統模擬軟體例如pspice中的等效電模型,而是從模型方程出發,採用數值模擬的方法,提高了模擬的精度。第四章和第五章分別建立了mos晶體管低頻、中頻、高頻的小信號模型,雖然借鑒了pspice模擬軟體中用等效電模型的方法,但是本文分別討論了準靜態和非準靜態時件的本徵部分以及包含非本徵部分工作于低頻、中頻和高頻條件時的模型,可以根據這些模型編寫相應的模擬軟體,這在做件的模擬分析與件設計的時候,就可以利用模擬軟體逐步深入地分析件在不同的條件下和件的不同部分在工作時的各種小信號特性,有利於抓住件工作的本質特性,設計出符合要求的各類通用和特殊件。
  2. The main chip of the usb interface circuit is a cypress semiconductor ' s product, cy7c64613, which has intergrated usb sie ( serial interface engine ) and enhanced 8051. the oscilloscope module is realized according to the real time sampling principle. it has two signal chunnels and a dual 8 - bit dual a / d converter whose most sampling rate is 40msps, so two signal acquisition can occurs in the same time

    隨后介紹虛擬儀測試平臺中各硬體模塊設計實現: usb介面的主晶元是cypress公司的cy7c64613 ,此晶元集成了usbsie和8051核;示波模塊根據實時原理實現,採用雙8位a / d轉換,提供兩條信號通道,可以同時採集雙信號,最高的采率為40mhz ;信號源模塊採用接數字合成( dds )原理實現,它所能產生的信號頻率為10hz 5mhz ,最小頻率解析度為9 . 537hz 。
