• Abstract: This paper reports the experimental characterization at the cryogenic temperature of a compact mm-wave broadband single-pole single-throw (SPST) switch in 22nm FDSOI CMOS technology. The switch consists of two n-MOSFETs with a special device option to reduce the substrate parasitic effects, and a third n-MOSFET to improve isolation. Unlike prior wideband mm-wave switches, it does not require any large passive components, allowing a very compact design, low loss and high isolation performance. The cryogenic measurements at 2 K show an insertion loss lower than 2.3 dB, an isolation better than 25.3 dB, and the return loss better than -11.5 dB, over the entire frequency range from DC to 70 GHz.

  We investigate the required peripheral circuits to enable ideal performance for a high-gain travelling-wave parametric amplifier (TWPA) based on three-wave mixing (3WM) By embedding the TWPA in a network of superconducting diplexers, hybrid couplers and impedance matching networks, the amplifier can deliver a high stable gain with near-quantum-limited noise performance, with suppressed gain ripples. We demonstrate how the WIF-TWPAs can be used to construct controllable isolators with over 40 dB isolation over the full 4-8 GHz band.

  We explore a prototype of an oscillatory neural network (ONN) based on vanadium dioxide switching devices.

In the case of a strong thermal coupling, the limit of the supply current parameters, for which the oscillations exist, expands by 10 %. The effect of subharmonic synchronization hold promise for application in classification and pattern recognition.
