Abstract
A high-performance superconducting digital-to-analog (D/A) converter providing asynchronous high-speed, low-power D/A conversion. The high-performance superconducting D/A converter includes a double-junction superconducting quantum interference device (SQUID) voltage divider circuit, which generates a series of discrete binary voltages, and a double-junction SQUID voltage selector circuit, which selects the binary voltages in accordance with a digital input signal. The currents generated by the selected binary voltages are added together to produce an analog output current that represents the digital input.
