摘要：
The development, fabrication, performance and applications of liquid nitrogen cooled voltage amplifiers based on high temperature superconducting quantum interference devices (SQUID) were discussed. Bias reversal was used to reduce the low frequency current noise of the voltage amplifier. It was shown that the voltage amplifier works for both liquid nitrogen cooled sources at room temperature.
