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 (ft and fmax) tend to increase with temperature. In addition, the inherent body-related parasitics and the series resistance have much more impa...
