F. Faccio et al., NOISE CONTRIBUTION OF THE BODY RESISTANCE IN PARTIALLY-DEPLETED SOI MOSFETS, I.E.E.E. transactions on electron devices, 45(5), 1998, pp. 1033-1038
An additional noise component is observed in the noise spectrum of tra
nsistors in a partially-depleted (PD) medium-thickness SOI-CMOS techno
logy. We identify the origin of this additional noise in the noisy res
istance of the body film. This resistance, coupled to the gate capacit
ance, forms an RC filter and generates the hump-shape of the additiona
l noise component. Several experimental observations that support this
model are presented.
