WebWe describe the various system components and present the results of our FPGA algorithm, including a novel approach with flexible working points and a combination of locking, flux jumping, and further digital signal processing. The DFLL has several advantages to conventional systems particularly for multisensor applications. WebAbstract Linear operation of SQUID sensors is normally provided by a flux-locked-loop, FLL, which provide a negative feedback mode of operation [1]. In the FLL, the signals are amplified, phase sensitively detected, filtered, integrated, and the resulting analog signal provides a measure of the magnetic field and noise in the SQUID output. green aesthetic color code
