摘要
This paper presents the design of cryogenic CMOS low-noise amplifiers (LNAs) using the concept of noise canceling (NC) for scalable, large-scale quantum computing applications. Various circuit topologies incorporating common-source (CS) and common-gate (CG) with the NC technique are introduced, based on our recent works in CMOS technologies. A comparative analysis of CS and CG noise-canceling techniques is presented, and different design techniques, including cascode inverter, self-body bias, input-referred noise reduction, and G m -boosting are discussed. The proposed cryo-CMOS LNAs using the noise canceling techniques achieve excellent noise figure, high gain, and wide bandwidth under low power consumption, demonstrating FoMs among the best. The design concepts provide directions for future LNA research for quantum computing applications.
