Variable-temperature attenuator calibration method for on-wafer microwave noise characterization of low-noise amplifiers
Anthony J. Ardizzi, Jiayin Zhang, Akim A. Babenko +2
Low-noise cryogenic microwave amplifiers are widely used in applications such as radio astronomy and quantum computing. On-wafer noise characterization of cryogenic low-noise trans…
Investigation of Cryogenic Current-Voltage Anomalies in SiGe HBTs: Role of Base-Emitter Junction Inhomogeneities
Nachiket R. Naik, Bekari Gabritchidze, Justin H. Chen +3
The deviations of cryogenic collector current-voltage characteristics of SiGe heterojunction bipolar transistors (HBTs) from ideal drift-diffusion theory have been a topic of inves…
Self-heating of cryogenic high-electron-mobility transistor amplifiers and the limits of microwave noise performance
Anthony J. Ardizzi, Alexander Y. Choi, Bekari Gabritchidze +4
The fundamental limits of the microwave noise performance of high electron mobility transistors (HEMTs) are of scientific and practical interest for applications in radio astronomy…
