中文拼音 [dānzuòyòngzēngyāqì]
單作用增壓器
英文
single shot booster-
The paper lays a strong emphasis on discussing the realization of the autocontrol of raster scanning of the scanner in x - y dimension, the " tapping " of the cantilever of the tappingmode afm by a direct digital synthesizer. then a method of parallel communication between dsp and pc in epp mode is given. finally, the author discussed the digital pid closed loop control of the scanner in z - direction, the automatic approaching of the tip using step - motor, and also some electro - magnetic interferences
論文首先簡單介紹了掃描探針顯微鏡的發展、分類、工作原理及應用；接著對ti公司的tms320vc5402dsp的特點及外圍擴展作了簡單介紹；然後分章節重點講述了利用vc5402dsp實現掃描探針顯微鏡的核心部件? ?壓電陶瓷管的x向和y向的光柵掃描控制；藉助直接數字集成器（ dds ）實現輕敲式原子力顯微鏡的微懸臂的「輕敲」 ； vc5402dsp的主機介面（ hpi ）與pc機在增強并行口（ epp ）模式下的通信；論文最後還介紹了掃描管z向的數字pid閉環控制，步進電機的自動進針，並對實際出現的一些電磁干擾問題作了討論。In order to increase the occupating coefficient and reliability of digital experimental box, we improve its power supply by designing a simple, reliable overcurrent protecting circuit base on the analysis of its working principle
設計了一個簡單可靠的電源過流保護電路，分析了過流保護電路的工作原理，在此基礎上改進了數字電路實驗箱中穩壓電源電路，提高了儀器的使用效率，增強了可靠性Usually the low power operational amplifier is designed with rail to rail output stage, whose signal dynamirange is small, its output driving force is not strong, here it is designed with voltage displacement stage, and the strong driving force and the low power consumption in this circuit are achieved. with 5v single power, this amplifier consumes only several a, 100khz unity - gain frequency, achieves 80db dc open gain and 55 phase margin for a 100pf load capacitance and a 1m load resistance and other advantages
通常設計的低功耗軌對軌輸出運算放大器中，由於信號的動態范圍比較小，它的輸出驅動能力不強，這里設計的是採用電平位移電路同時實現了電路的強驅動能力與低功耗，它具有在單電源電壓5v的條件下，靜態工作電流只有幾微安，單位增益帶寬達100k ，開環增益能達80db以上，相位裕度也能達55度，輸出源沉電流達500微安以上等優點。
