Query: Small-signal parameters extraction and noise analysis of CNTFETs   The use of carbon nanotube (CNT) field-effect transistors (FETs) in microwave
circuit design requires an appropriate, immediate and efficient description of
their performance. This work describes a technique to extract the parameters of
an electrical equivalent circuit for CNTFETs. The equivalent circuit is used to
model the dynamic and noise performance at low- and high-frequency of different
CNTFET technologies, considering extrinsic and intrinsic device parameters as
well as the contact resistance. The estimation of the contact resistance at the
metal/CNTs interfaces is obtained from a Y-function based extraction method.
The noise model includes four noise sources: thermal noise, thermal channel
noise, shot channel noise and flicker noise. The proposed model is compared
with a compact model calibrated to hysteresis-free experimental data from a
high-frequency multi-tube (MT)-CNTFET technology. Additionally, it has been
applied to experimental data from another fabricated MT-CNTFET technology. The
comparison in both cases shows a good agreement between reference data
(simulation and experimental) and results from the proposed model. Low- and
high-frequency noise projections of the fabricated reference device are further
studied. Noise results from both studied technologies show that shot noise
mainly contributes to the total noise due to the presence of Schottky barriers
at contacts and along the channel.
