• range from DC to 17 kHz. We experimentally show that the parallel differential circuit design allows for a reduction of the voltage noise from 0.55 to 0.33 nV/Hz0.5 at 77 K. Keywords: cryogenic amplifier; cryogenic low-noise amplifier; differential cryogenic amplifier; superconducting circuit readout

• applications are based on dry cryostats instead of coolants. The most common modern dry cryostats, including dilution refrigerators and He-7 sorption refrigerators, have a 50 K temperature stage as uppermost cooling stage where the DC cryogenic amplifier can be mounted. In this paper, we show the potential

• voltage sources. The resistors R1 and R2 are the load resistors of the collector circuits, and the capacitor C5 is the decoupling output capacitor, which has the unwanted effect of reducing the frequency bandwidth at low frequencies. The resistors used in the cryogenic amplifier are MELF-type resistors
