Thermal Noise in MOSFETs: A Two- or a Three-Parameter Noise Model?

In this brief, it is clearly demonstrated that a two-parameter noise model is sufficient to accurately extract the MOSFET high-frequency noise performance, as long as channel uniformity is ensured (which corresponds to mainstream CMOS technology). Nevertheless, in the case of asymmetric channel-based MOSFETs, it is shown that a three-parameter noise model is required.
