| 摘 要： | 利用SPICE电路模拟研究了SET在传播过程中的脉冲展宽效应.结果表明,负载的不均衡、电路上/下拉网络驱动能力的不对称以及浮体效应是造成脉冲展宽/压缩的主要原因.本文从基本的上升/下降延迟计算出发,对脉冲展宽/压缩的机理进行了深入的分析,认为在负载均衡的条件下,SOI反相器链中的脉冲展宽效应主要归因于浮体效应和"局部"浮体效应.

| Abstract: | Propagation induced pulse broadening of single event transient is studied by SPICE simulation.It is demonstrated that an unbalanced output load,asymmetric current drive strengths of pull up/pull down networks,and floating body effects are the primary sources for pulse broadening/compression.Grounded on basic formulae of rise/fall propagation delay,the mechanism of pulse broadening/compression is analyzed.We point out definitely for the first time that propagation induced pulse broadening in an SOI inverter chain under a balanced output load is mainly due to floating body effects or local floating body effects. |
