Depiction of Circuit of Invention

AC and DC Bipolar Voltage Source Using Quantized Pulses

NIST Inventors
Samuel P. Benz and Charles J. Burroughs
This invention solves this problem. It is a Josephson circuit that provides accurate, stable, arbitrary waveform generation with a pre-determined frequency spectrum. It will enable the synthesis of both AC and DC bipolar waveforms, where voltage pulses of both positive and negative polarity are

Josephson Voltage Standard

NIST Inventors
Samuel P. Benz , Paul Dresselhaus , Alain Rufenacht and Anna Fox
It was determined that a device having simultaneous voltage reference signals would be useful for many measurement and calibration activities. A JVS advantageously having multiple output leads would meet this criterion, and provide such voltage references without the need for multiple systems
Depiction of superconducting waveform synthesizer.

Superconducting Waveform Synthesizer

NIST Inventors
Samuel P. Benz , Manuel Castellanos Beltran , Paul Dresselhaus and Pete Hopkins
We have 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 pulse timing shifts
