Design of a SQUID sensor having a SQUID amplifier
Eriko Takeda, Toshikazu Nishino · Superconductor Science and Technology · 1996
The frequency dependent characteristics of a SQUID amplifier have been studied by numerical simulation using a model circuit consisting of a SQUID sensor and SQUIDs connected in series. Optimization of the circuit parameters from the simulated results makes it possible to design the amplifier with wide bandwidth and low distortion.
