Abstract(in English) We proposed a new FLL circuit with bias current modulation scheme, and confirmed the function by using actual electronics with an SQUID. The proposed circuit is very simple construction, and doesn't need a complex component like PSD used in conventional modulation type circuits. From computer simulation study, we found it has potentials to reject the low-frequency voltage noise added to SQUID output, to work with non-symmetrical Φ-V characteristics with respect to the bias current and to suppress a part of the noise due to the SQUID.
