Abstract This paper has described a new concept on programmable switch device furnished with gain cell combined to FeRAM. Compared with memories but ferroelectric memories under many aspects, they have even been favorably labeled the ideal memory because of their non-volatility, ease of programming and operation by low voltage. As the programming switch, which is very attractive for logic application, SRAM, anti-fuse, flash type devices are well known. They have been required that satisfy non-volatility and low-voltage programming simultaneously. Some structures with ferroelectric material have been proposed and studied as solution of these problems. However, it seemed hard that these type devices are realized now from a viewpoint of fabrication process and low voltage operation. Therefore, we propose a new switch device furnished with gain cell combined to FeRAM. We have studied and simulated this switch device by SPICE. This basic circuit is composed of two blocks. One is switching block that includes gain cell, and the other is memory block that is FeRAM. Circuits, which we designed, amplify bit line's voltage up to Vdd or ground at sense amplification according to FeRAM data. The bit line voltage determines the logic state for gate electrode of switch transistor. The way to read is destructive read out. However, we can transfer information of bit line voltage during plate line is low-level voltage. The way to write FeRAM is similar to conventional way. It is revealed that the basic circuit with FeRAM connected gain cell could work correctly in simulation. In addition, this kind of device is hopeful of many logic applications. 相似文献

Abstract Smart materials of lead-zirconate-titanate (PZT) piezoelectric ceramics have attracted attention in recent years for active vibration control, acoustic noise suppression, health monitoring and damage assessment. We at McDonnell Douglas Aerospace have been studying these ceramics for use as sensors and actuators in various space and aircraft structures. In this paper, we will report results of a recent study on active vibration control using monomorph PZT actuators. The experiments were performed on thin aluminum cantilever beams. Collocated and non-collocated sensors and actuators were employed. Two control techniques: the classical velocity feedback and adaptive feedback controls, were investigated. We have obtained significant damping and broadband vibration attenuation of greater than 30 dB using the classical control with the single-input single-output feedback approach. A 24 dB reduction has also been achieved using the adaptive control with the multiple-input single-output approach. Detailed experimental methods and results will be described. 相似文献

电纺丝技术及其应用 总被引:2,自引:0,他引:2
电纺丝技术是非牛顿流体的高聚物溶液在高压电场的作用下克服表面张力和粘弹性力,进行拉伸弯曲运动获得纳米到亚微米级纤维的一种技术。它作为高压与纳米技术的完美结合为传统高电压技术注入了新鲜血液。电纺丝纤维因其巨大比表面积和高孔隙率而得到组织工程、同轴电缆、药物缓释等多领域的关注。电纺丝参数影响方面的报道很多,而电纺丝领域当前最前沿研究及最新发现的报道还很少,故介绍了国内外电纺丝参数的研究成果及其最新动态,提出了电纺丝发展的几个瓶颈问题及解决方向。说明电纺丝技术的发展必然要先从理论模型和提高效率两方面入手并取得足够进展,该技术才能在生产实践中广泛应用。 相似文献

1000 kV GIS变电所VFTO特性研究 总被引:28,自引:10,他引:18
为确保特高压输电工程的安全可靠,结合我国特高压输电试验示范工程计算分析了GIS和HGIS变电所的特快速瞬态过电压(VFTO)。研究表明,GIS变电所隔离开关开合短线时可能产生高达3p.u.左右的VFTO,对GIS本体绝缘和二次设备可能构成危害。研究了GIS隔离开关装并联分合闸电阻对限制VFTO的作用后,建议GIS变电所采用并联分合闸电阻(约500Ω),提出了并联分合闸电阻的相关参数的建议值;GIS变电所中的主变压器和GIS是经架空线相连接,在变压器上的VFTO不高;HGIS变电所中的VFTO不高,在允许范围内,其隔离开关可不装并联分合闸电阻。 相似文献

特高压线路工频参数测试干扰分析是选择适合工频参数测试方法及测试结果分析的重要基础。测试了1 000 kV皖南-浙北特高压线路正序和零序参数测试期间的干扰电压信号,分析了其频谱特征;在此基础上,通过与正序参数仿真计算值的对比分析了正序参数实际测试偏差。结果表明:皖南-浙北特高压同塔双回线路工频参数测试期间,干扰电压存在“三相不平衡性及时变性”的特点;工频法和异频法2种不同方法得到的线路参数测试结果存在一定差异;干扰电压“时变”时,线路工频参数测试宜采用异频法。 相似文献

Rate design serves objectives of cost recovery, market animation, and customer incentives. Yet in the quest to find the ‘perfect equitable rate,’ many rate designers and pilots overlook the diversity of consumer attitudes. AMI enables not only interval monitoring and controls, it allows alternative pricing plans, payment options, device adoption, and generation mixes reflecting individual priorities. Connecting consumer attitudes with a portfolio approach helps regulators and utilities achieve specific goals while improving satisfaction and engagement. 相似文献
