摘要
作者使用了由集成块所组成的电子线路来模拟Josephson结的性质,其特点是设计了一种新型的采样保存电路来模拟与sinθ成正比的超导电流.这种电子线路模拟能很快地显示出结的特性.
An IC electronic circuit is used to analogize the behavior of Josephson junction. A novel method based on a sample-and-hold circuit to generate the sinθ supercurrent is designed. This electronic analogy has an advantage in demonstrating the qualitative behavior quickly and gives quantitative results more easily than using digital computer to solve a nonlinear differential equation.
