Resumen:
In this work, we present the design and first characterization of an operational amplifier for use at cryogenic temperatures. We show the functionality of the amplifier in a range of temperatures from 12.5K to 273K. Drain current to gate voltage curves of n-channel and p-channel MOS transistors, resistors and the amplifier response were measured. The circuit allows the amplification of signals up to 100kHz with a power consumption of 48μW.
