端面流体膜密封的浮环半频摆动自振特性是其一种固有属性,类似于径向流体膜轴承中的“半速涡动”。基于流体流动连续性原理,对端面流体膜密封角向摆动自激振动的产生及其半频特性的机理提出了一种简化力学的阐释。

The parasitic capacitance effect and its influence to the performance have been investigated in Bi-polar Junction Metal-Oxide-Semiconductor Field-Effect Transistor (BJMOSFET). The frequency characteristic equivalent circuit and high frequency response model of BJMOSFET have been presented. The frequency characteristic of BJMOSFET is simulated using the multi-transient analytical method and PSPICE9 simulator. The conclusions that BJMOSFET owns less total capacitance, wider frequency band, better transient charac-teristic and better frequency responses are reached by comparing with the traditional MOSFET at the same structure parameters and bias conditions. BJMOSFET, as a novel promising high frequency device, would be desired to find application in future integrated circuit. 展开更多
