All rights received.The linearity of Junctionless nanowire transistors operating in the linear regime has been evaluated through experimental data and numerical simulations. The influences of the fin width, the gate bias, the temperature, the doping concentration and the geometry on the overall linearity have been evaluated. The increase of the series resistance associated both to the variation of the physical parameters and the incomplete ionization effect has shown to improve the second order distortion and degrade the third order one.- Impact of asymmetric channel configuration on the linearity of double-gate SOI MOSFETs(2006-04-26) Marcelo Antonio Pavanello; CERDEIRA, A.; MARTINO, J. A.; RASKIN, J. P.; FLANDRE, D.In this paper the linearity of asymmetric channel double-gate transistors, using the graded-channel (GC) configuration and Gate-All-Around architecture, operating as an amplifier, is studied in terms of lightly doped region length. The total harmonic distortion and third-order harmonic distortion are used as figures of merit. The results are compared with single-gate transistors with similar channel configuration. It is demonstrated that double-gate GC transistors at the same operation region and with similar channel configuration can present up to 20 dB less total harmonic distortion while presenting small third-order harmonic distortion. Considering similar bias voltage, the alternate component of the input sinusoidal signal of GC double-gate devices can be increased by about 200 mV to provide similar third-order harmonic distortion maintaining similar improvements of 20 dB on the total harmonic distortion. © 2006 IEEE.
