  • Interfacing at low temperature using CMOS technology
    Patent number: 7911265
    Abstract: This invention concerns interfacing to electronic circuits or systems operating at low temperature or ultra-low temperature using complementary metal-oxide semiconductor (CMOS) technology. Low temperature in this case refers to cryogenic temperatures in particular, but not exclusively, to the 4.2 K region. Ultra-low temperatures here refers to the sub-1 K range, usually accessed using dilution refrigerator systems. The electronic circuits comprise a controller (for writing and manipulation), an observer (for readout and measurement) circuits, or both, fabricated from ultra-thin silicon-on-insulator (SOI) CMOS technology.
    Type: Grant
