摘要
In this paper, temperature-dependent RF small-signal and noise characteristics of silicon-on-insulator (SOI) dynamic threshold voltage (DT) MOSFETs are experimentally examined. In the low-voltage regime, both the cutoff and maximum oscillation frequencies (f(t) and f(max)) tend to increase with temperature. In addition, the inherent body-related parasitics and the series resistance have much more impact on f(max) than f(t). Besides, we found that the noise stemmed from the body resistance (R-b) would contribute to the output noise current, and degrade the minimum noise figure (NFmin). Our study may provide insights for RF circuit design using advanced SOI DT MOSFETs.
