Abstract :
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.
