“…Because such excess noise effects are field-driven [14], it could be expected that they would increase sharply when entering the sub-100-nm regime, where channel length scales down much more rapidly than supply voltage, resulting in large lateral electric fields. Indeed, larger deviations from pure thermal noise have been experimentally observed in sub-100-nm channels [15], [16], while in extremely short channels (10 nm) full shot noise was measured [17]. In [18], where noise data of a large number of sub-100-nm devices from various foundry processes was analyzed, we demonstrated that this microscopic excess noise leads to a remarkably universal increase in thermal noise for decreasing channel length.…”

“…7, along with the output of Eq. (16) fitted to the data from Patalay et al 9 Agreement is found in the noise behavior and the gradual suppression of shot noise at the higher V GS value.…”

“…6 The transition between the two noise regimes in terms of the applied bias has been extensively documented as well. 7 Recently, new experiments have been carried out with ultra-short devices, 8,9 introducing the concept of shot noise in nanoscale MOSFETs. The new-found results are similar in nature to those observed in thermionic valves and silicon diodes.…”

“…Additionally, it is proven that for constant V DS , δ decreases when V GS increases. Thermal noise parameter seems to increase for n-MOS devices down to 40 nm, recently reported in [173,183,207] for operation in strong inversion and saturation.…”
