The unshunted (un) SQUID (superconducting quantum interference device) is a novel device with a frequency-dependent damping on the Josephson junctions. The un SQUID circuit contains four adjustable parameters, including equivalents of the βc and βl in dc SQUIDs. We have studied numerically the effect of the parameters to the un SQUID characteristics. To solve the Langevin equations, explicit Euler integration is used. We have also mapped the device noise as a function of the parameters. The energy resolution of the un SQUID appears to be better than that of the dc SQUID.
