Impact of Subthreshold Carrier Statistics on the Low-Frequency Noise in MOSFETs
Low-frequency noise analysis is being used as a method to understand the nature of carrier transport in new material-based devices and to improve the sensitivity of sensors operating in the subthreshold regime.

| Summary: | Low-frequency noise analysis is being used as a method to understand the nature of carrier transport in new material-based devices and to improve the sensitivity of sensors operating in the subthreshold regime. In this paper, we show that the (gm/Id)2 method used in carrier number fluctuation based noise formulation needs modification in the subthreshold regime. Based on the new formulation, many published results may require reinterpretation. The new formulation is validated with data extracted from the literature for III-V, nanowire, and high-K gate-stack-based devices. |
