Title:
JOSEPHSON ANALOG-TO-DIGITAL CONVERTER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/219142
Kind Code:
A3
Abstract:
One example includes a Josephson analog-to-digital converter (ADC) system. The system includes a control line inductively coupled to an input signal line on which an input analog signal is provided. The input signal line can be inductively coupled to the control line to propagate an induced input current that is based on the input analog signal on the control line. The system also includes at least one Josephson transmission line (JTL) stage that is biased via a DC bias current and is configured to generate an output pulse in response to the induced input current and the DC bias current exceeding a predetermined threshold current associated with the at least one JTL stage.
