Abstract

In order to investigate the characteristics of a dc SQUID coupled to a multiturn input coil, resonances occurring in this configuration, such as input coil resonances and washer resonances, are studied using the expanded model of the coupled SQUID. These resonances are shown to be suppressed well using proper damping resistors. The expressions for the optimum damping resistors have been obtained as a function of SQUID parameters. It is also shown that the optimum values of the damping resistors depend on the configuration of the SQUID washer. Based on the results obtained for the resonant properties, we discuss the design of highly sensitive dc SQUIDs coupled to the multiturn input coil.
