Dynamic behavior of dc SQUID coupled to resonant circuit is studied with numerical simulation. It is shown that large rf noise flux is caused by the resonant circuit, and is added to the SQUID. This rf flux affects considerably the SQUID characteristics, e. g., appearance of resonant behavior and the increase of noise. It is also shown that a parasitic capacitance between the resonant circuit and the ground of the SQUID changes the SQUID characteristics. Therefore, it is important to suppress the rf noise flux and decrease the parasitic capacitance in order to improve the characteristics of the coupled SQUID.
