摘要

Bias non-conservation characteristics of high-frequency noise of 40nm n-MOSFETs are identified by measuring its drain current noise. Measurement results over a wide temperature range demonstrate the existence of thermal noise of 40nm n-MOSFETs in the weak and low middle inversion region, contrary to the predictions of suppressed shot noise model only suitable in the strong inversion and high middle inversion region. These new findings on the noise mechanisms of 40nm n-MOSFETs are very beneficial for its ultra low-voltage low-power RF application, such as noise analysis, circuit design and process technology evaluation.
