摘要

This paper presents a low-power, inductorless wideband cryogenic amplifier for superconducting nanowire single photon detector. To achieve wide bandwidth, low power consumption and small chip area, a modified Cherry-Hooper amplifier topology is used. With good input and output match, at 4.2 K temperature the measurement results show that the amplifier achieves 23-dB gain with a flat gain response,...
