摘要

In this paper the amplifying properties of operational amplifiers (bipolar, Bi-FET and CMOS) in the function of temperature are presented and discussed. We measured operational amplifiers between 300 K and 4 K. The Bi-FET opamps work well in the temperature range down to 60-70 K. The CMOS operational amplifier (type of AD8594) operate correctly in the whole temperature range from 300 K to 4 K.
