Abstract
A set of components for a direct coupled SQUID electronics was designed and fabricated in silicon semiconductor BiCMOS technology and optimized for liquid nitrogen temperature. The most crucial part, the preamplifier has a white noise level of 0.44nV/√Hz and shows small power dissipation. A complete liquid nitrogen cooled SQUID electronics operates successfully with a HTS dc-SQUID.
