  1. Secondly, compared with some other kinds of comparator structure and based on the preamplifier - latch fast - compare theory, a novel topology of cmos preamplifier latch comparator circuit is presented. considering trade - off between kickback noise and power dissipation, reference resistance value is optimized. according to the encode demands of different stage resolution, clock - control encode circuit is designed

    其後,在具體的子adc設計中,對比各比較器類型的優缺點,並基於預放大鎖存快速比較理論,提出一種新型高速低功耗預放大鎖存比較器路拓撲;根據adc系統所允許的參考最大波動限,在回饋噪聲對輸入參考平的影響和功耗之間折衷,確定優化的參考阻串阻值;根據不同級精度的編碼要求,設計出編碼路。
  2. According to the request of this subject, we have developed the system hardware and software for the slave device and the inspection software running on the pc. in this paper all of the followings is illustrated detailedly, such as the research on the principles of measurement and its realization, three means of water - level measurement that are separately based on photo electricity coder, pressure sensor and potentiometer ; selection of the microchip, we choose an advanced integrated soc ( system on chip ) microchip c8051f021 as the main controller ; realization of signal sampling, processing and its conversion in the mcu ; application of high precision 16 bits adc cmos chip - - ad7705 in our system, designing its interface with the microchip and relevant program ; using a trickle charge timekeeping chip ds1302 in the system which can provide time norm and designing of its i / o interface and program ; additionally, a 4 ~ 20ma current output channel to provide system check - up using ad421. in the system, ad421, ad7705 and the microchip compose spi bus ; to communicate with the master pc, here we use two ways which are separately rs232 and rs485 ; moreover, there are alarm unit, keyboard unit, power supply inspection unit and voltage norm providing unit in the system

    針對研製任務的要求,課題期間研製了下位機系統硬體和軟體,開發了上位機監軟體,其中所作的具體工作包括:測量原理的研究和在系統中的實現,在本次設計中用三種方法來進行水位測量,分別是旋轉編碼器法、液位力傳感器法和可變阻器法;主晶元的選擇,我們選用了高集成度的混合信號系統級晶元c8051f021 ;實現了信號的採集和處理,包括信號的轉換和在單片機內的運算;高集成度16位模數轉換晶元ad7705在系統中的應用,我們完成了它與單片機的介面設計及程序編任務;精確晶元ds1302在系統中的應用,在此,我們實現了用單片機的i o口與ds1302的連接和在軟體中對序的模擬,該晶元的應用給整臺儀器提供了間基準,方便了儀器的使用;另外,針對研製任務的要求,還給系統加上了一路4 20ma模擬信號流環的輸出路來提供系統監測,該部分的實現是通過採用ad421晶元來完成的,本設計中完成了ad421與單片機的spi介面任務,協調了它與ad7705晶元和單片機共同構成的spi總線系統的關系,並完成了程序設計;與上位機的通信介面設計,該部分通過兩種方法實現: rs232通信方式和rs485通信方式;系統設計方面還包括報警路設計、操作鍵盤設計、源監路設計、基準路的設計。
  3. In the time - domain, based on the principle of random sampling of dso. two way ( " time amplifing in dual slope integral " and " time - voltage convert " ) are implemented to measure the time between the system triger and writing clock. thus random sampling interpolate can be done to measure repeated signal in high frequency with the a / d convert and controller which frequency are lower
