Flux locked loop
WebThe natural flux signal range of SQUIDs is limited to the–¼F 0 monotonous range. This has been traditionally extended by negative flux feedback, either locally [2, 3] or via room-temperature electronics [4] in the so-called flux-locked loop (FLL) configuration. In the local feedback, unfortunately, the output signal level is lowered so WebAug 20, 2024 · The sine wave output of the lock-in amplifier was sent to the excitation coil to produce the excitation magnetic field. The excitation frequency was 20 kHz and the current amplitude was 20 mA. ... “Linearity of high-T c dc superconducting quantum interference device operated in a flux-locked loop,” Journal of Applied Physics, vol. 80, no ...
