Abstract
Kinetic inductance traveling-wave parametric amplifiers (KITs) are under development for the read out of large cryogenic detector arrays. We present new KIT designs based on 20nm NbTiN films patterned by use of standard optical photolithography. We report device gain, bandwidth, and noise properties, which approach the quantum limit. In addition, we demonstrate a KIT preamplifier with a microwave SQUID multiplexer. The improved input referred current noise, as compared to standard HEMT readout, opens up new possibilities for cryogenic receivers. We discuss these benefits.
