Challenges and Approaches for Mixed-Signal Cryogenic CMOS Design

CMOS design targeting temperatures as low as 4 K has seen a renewal of interest due to the rapid evolution of quantum computers that make use of cryogen-enabled qubit technologies. This workshop tutorial will explore concepts in design at these temperature points, including a survey of characterization results of different CMOS technologies at cryogenic temperatures and discussions of the challenges and opportunities for analog, RF, and digital circuitry.
