A planar picoamperemeter based on a superconducting quantum interferometer
Artikel i vetenskaplig tidskrift, 2006

An optimized picoamperemeter based on a superconducting quantum interferometer device (SQUID) for a metal cold-electron bolometer is fabricated and experimentally studied. The intrinsic SQUID current noise caused by the input coil is estimated to be less than 1 pA/Hz@1/2. Owing to the application of modulation electronics, current sensitivity in the input coil reaches 5 pA/Hz@1/2 in the frequency band from 10 Hz to 10 kHz.
