英文摘要潤色(電子類)
|
|
本人有一篇中文摘要,個人感覺翻譯的不是很好,希望蟲友們潤色一下,謝謝![]() ![]() ![]() 以典型的Si基n+-p-n-n+雙極晶體管為對象,通過微波注入方式,從器件內(nèi)部電場強度、電流密度和溫度的分布變化出發(fā)研究其在高功率微波作用下的內(nèi)在失效機理。利用線性擬合方法得到了損傷功率和脈寬之間的關(guān)系。研究表明,高功率微波對雙極晶體管損傷部位是B-E結(jié)。燒毀點升溫主要集中在信號負(fù)半周著信號注入幅度的不斷增加,在正半周期燒毀點溫度下降幅度越來越慢,注入幅度增加到一定值時,溫度有小幅升高。損傷功率和脈寬公式和短脈沖經(jīng)驗公式符合的很好,從而驗證了器件模型的合理性。 In this paper the study of high power microwave injection effect and internal damage mechanism of the typical n+-p-n-n+ structure bipolar transistor is investigated from the variation distribution of the electric field, the current density and the temperature. The relationship between the burnout time and the damage power is obtained using the curve fitting method. Results indicate that the damage position of the bipolar transistor is the base-emitter junction where the temperature rising is focus in the negative half-period. In the positive half-period, as the injected signal peak increases, the magnitude of the temperature falling in the damage position decreases but the temperature rises slightly when the injected singal peak increases to a certain value. The relationship of the damage power and the burnout time fits well with the empirical formulas which proved the accuracy of our model. |

The first sentence is modified as below: 以典型的Si基n+-p-n-n+雙極晶體管為對象,通過微波注入方式,從器件內(nèi)部電場強度、電流密度和溫度的分布變化出發(fā)研究其在高功率微波作用下的內(nèi)在失效機理。 In this paper, the internal damage mechanism of the typical Si based n+-p-n-n+ structured bipolar transistor under high power microwave injection is investigated by studying the variation and distribution of the electric field, current density and temperature inside the transistor. |
