本文介绍了一种全干法二步刻蚀制造高发射效率的场发射阵列(FieldEmitterArrary-FEA)的方法。首先利用等离子刻蚀(PlasmaEtching-PE)的各向同性在由SiO2掩模的硅衬底上刻出平顶尖锥,然后再利用反应离子刻蚀(ReactiveIonEtching-RIE)的各向异性,在PE的基础上进一步刻蚀来拔高尖锥并减少尖锥顶部的面积,以得到理想形状的FEA尖锥。这种方法比RIE一步刻蚀法和湿法刻蚀加RIE二步法简单可靠。 相似文献

DPAD2 is a Field Programmable Analog Array (FPAA) based on CMOS switched capacitor technology. This paper describes the major design decisions that went into creating DPAD2 with respect to the ultimate goal of the work, being a mixed signal field programmable silicon solution. Two major compromises exist in the design of an FPAA, one between flexibility and performance, the other between functionality and die size; DPAD2 overcomes the first with a novel field programmable hierarchic routing scheme and the second by careful analysis of many disparate designs to arrive at a best compromise solution. Results from prototype silicon are presented where a single analog cell is reconfigured to perform a number of different analog signal processing functions. Bandwidth of the DPAD2 device is 500 kHz and the SNR is typically 60 dB, although both are application dependent. Introduction of the FPAA now enables a designer to have working silicon within one day, by a simple configuration of the silicon chip via a PC parallel interface. Software libraries of analog circuits are provided and allow very rapid creation of large and complex analog circuits. 相似文献

A new method for solving electromagnetic field boundary value problem is given.Byusing this method,the boundary value problem of the vector wave equation can be transformedinto the independent boundary value problem of scalar wave equations and the two additionalvector differential operations.All the dyadic Green's functions got by eigenfunction expansionof the dyadic Green's function can be got by this method easily and some of the dyadic Green'sfunctions for complex systems which are very difficult to get by the ordinary method have beengot by this new method.The dyadic Green's function for a dielectric loaded cavity is one of thegiven examples. 相似文献

双光纤布拉格光栅磁场传感器 总被引:1,自引:0,他引:1
载流导线在磁场中产生的电磁力使等腰三角形悬臂梁变形,从而导致安装在悬臂梁两边的光纤布拉格光栅(FBG)的布拉格波长漂移.通过检测2个FBG的波长漂移差,得到被测磁场的磁感应强度.双FBG通过补偿温度效应,解决了FBG传感器的交叉敏感问题.垂直放置的等腰三角形悬臂梁,确保FBG在传感过程中不出现啁啾现象,又避免了自身重量和导线重量对测量结果的影响,从而减少了测量误差.该系统传感灵敏度为1.11 nm/T,与理论值的相对误差为4.31%,结果表明,该传感器结构是可行的. 相似文献

一种改进的有限差分光束传输法 总被引:4,自引:2,他引:2
改进了传统的有限差分光束传播法(FF-BPM),实现了一种新的基于近似传播常数的FD-BPM。该算法与传统方法相比,无论是在计算精度、收敛速度,还是在计算稳定性方面都得到了有效的提高;在传统解析求解方法失效的情况下,该方法在求解复杂折射率分布光波导的传播常数也具有较高的理论参考价值。 相似文献
