Superconducting Waveform Synthesizer

NIST Inventors
Samuel P. Benz , Manuel Castellanos Beltran , Paul Dresselhaus and Pete Hopkins
Patent Description NIST has invented a pulse quantizer that uses arrays of one or more Josephson junctions to create a pulse voltage output that is immune to differential pulse timing shifts. When the output pulse patterns are used to encode a waveform, for example, the waveform will be free from

Phase Transition Based Resistive Random-Access Memory

NIST Inventors
Albert Davydov , Sergiy Krylyuk and Huairuo Zhang
Patent Description This invention relates to memory devices, in particular to resistive random-access memory (RRAM) cells. RRAM-based technology has gained attention of the semiconductor industry due to its potential scalability, high operation speed, high endurance and ease of process flow. RRAM

Optical Phantom for Producing a Time-Resolved Diffuse Reflectance Spectrum

NIST Inventors
Jeeseong C. Hwang
Patent Description Physikalisch-Technische Bundesanstalt (PTB) and NIST jointly developed a concept for a waveform synthesizer which can generate a controlled waveform with several picosecond (ps) time resolution. In a light-diffusing material, characteristics of the time-of-flight distribution (e.g

Thermal Impedance Amplifier

NIST Inventors
Adam McCaughan , Varun Verma , Sonia Buckley and Sae Woo Nam
Patent Description Presently, superconducting electronics are being applied to areas such as computational backends for future quantum processors, high-performance supercomputing, and ultrafast digital signal processing. In all of these areas, data must be communicated between the superconducting

Neural Member, Neural Network, and Neurological Memory

NIST Inventors
Stephen E. Russek , William Rippard and Matthew Pufall
Patent Description We propose a new form of artificial synapse based on dynamically reconfigurable superconducting Josephson junctions with magnetic clusters in the barrier. The spiking energy per pulse varies with the magnetic configuration. The critical current of each magnetic Josephson junction

Phase Shift Detector Process for Making and Use of Same

NIST Inventors
Kin (Charles) Cheung , Jason Ryan and Jason Campbell
Patent Description The new NIST detector senses very small phase shifts in a highly balanced microwave bridge. An electric field optimized microwave probe, in close proximity to a sample, serves to perturb the degree of bridge balance due to a change in effective dielectric constant of the sample
