Far-infrared (IR) focal plane arrays are becoming increasingly important for terrestrial and space-based imaging applications. For noise reasons, it is desirable to have transresistance preamplifiers at the focal plane, and, therefore, they need to operate over wide temperature ranges. High-temperature superconducting (HTS) amplifiers that have a high gain, relatively low noise, and response times of <200 ps over at least a 10-80-K temperature range have been developed.<>
