This article relates generally to superconducting, waveform sampling systems and more specifically to superconducting, waveform sampling systems which utilize nonhysteretic cryogenic devices such as a nonlatching Josephson junction or a three-terminal device such as a Quiteron [*]. Fig. 1 shows a partial schematic, partial block diagram of a superconducting, waveform sampling system 1, which utilizes a nonhysteretic Josephson junction D, for example. As shown in the I-V characteristic of Fig. 2, device D is biased by a current Ig and a control current Icontrol so that it operates in its nonzero voltage state at a voltage Vg. Icontrol, when it alone flows in control line 2, causes device D to operate in its voltage state.
