Abstract

The embodiments herein describe technologies of an amplifier circuit that is designed for wideband communication with superconductive components in cryogenic applications, including Josephson Junction integrated circuits, operating in a cryogenic temperature domain (e.g., 4K). The amplifier circuit operates in a temperature domain (e.g., 77K) that is higher than the cryogenic temperature domain of the superconductive components.
