Abstract

A superconducting pulse discriminator based on a cascade switch to the normal state ofparallel ultrathin NbN nanostrips has been fabricated and carefully investigated.Correct operation was achieved using 1 ns input pulses with amplitudes down to15 µA. The discriminator had a peak current gain of 12 and an FWHM timing jitter of 80 ps,limited by our measurement instrument resolution. These characteristics, together withsimple on-chip integration, small area and low dissipation, make this device suitable forapplications such as readout of fast cryogenic detectors and the output stage ofsuperconducting digital circuits.
