Abstract :
A superconducting 3-terminal device based on NbN ultra-thin nano-strips has been realized. The device is capable of pulse discrimination and shaping and provides power gain with standard 50 Ω input and output impedance. It operates at 4.2 K and is well suited for the realization of output interfaces for superconducting digital circuits and as readout of cryogenic detectors. Successful realization of the integrated readout of a nano-strip single photon detectors is reported.
