摘要

我们通过电压响应分析了双SQUID的噪声特性，并与开环配置下的直流SQUID的特性进行了比较。在bi-SQUID中增加的Josephson结提供了额外的波动源、变化传递函数、非线性动力学和非线性噪声谱变换。这些导致不同的输入噪声水平与施加的磁通量。

Bi-SQUID noise simulation

We present an analysis of noise characteristics of bi-SQUID through its voltage response and compare to characteristics of dc SQUID in the open loop configuration. The additional Josephson junction in bi-SQUID gives an additional source of fluctuations, changes transfer function, nonlinear dynamics and nonlinear noise spectrum transformation. These result in different input noise level versus applied magnetic flux.
