Abstract:A significant number of cryogenic low-noise amplifiers (cryo-LNAs) are required for the readout of superconducting nanowire detector (SNWD) arrays. It is desirable to have compact cryo-LNAs in place so that the size of the readout circuitry for the SNWD array can be reduced. In this study, we first examined the bandwidth, linearity, and noise requirements of the cryo-LNA for SNWD readout. After that, the design and implementation of a wideband silicongermanium (SiGe) BiCMOS cryo-LNA were described in detail. T… Show more
