“…In back-gated structures, due to different junction and overlap capacitances, high-frequency operation is limited but the top-gate edifice of CNFET permits high-speed operation. Also, due to inbuilt channel of nanotubes and its structure, leakage current is no longer the problem with CNFET and it shows enhanced current handling competency [24][25][26]. CNFET endeavours remarkable carrier transport and conduction characteristics predominantly due to the high mobility and high current density [25][26][27].…”

“…is trend is observed because CNFET circuit performance and electrical behaviour directly depend on the CNT diameter. Diameter is the main parameter that affects the on current proportionally in a CNFET apart from barrier height at the S/D contact (or RS/D), chirality, and oxide thickness, but for larger diameters, current tends to saturate due to large screening and scattering effects [14,24,25,33]. Also, the power consumption of an amplifier goes up due to the smaller band gap and higher current drive.…”

Carbon nanotube (CNT) is one of the embryonic technologies within recent inventions towards miniaturization of semiconductor devices and is gaining much attention due to very high throughput and very extensive series of applications in various analog/mixed signal applications of today’s high-speed era. The carbon nanotube field effect transistors (CNFETs) have been reconnoitred as the stimulating aspirant for the future generations of integrated circuit (IC) devices. CNFETs are being widely deliberated as probable replacement to silicon MOSFETs also. In this paper, different analog signal processing applications such as inverting amplifier, noninverting amplifier, summer, subtractor, differentiator, integrator, half-wave and full-wave rectifiers, clipper, clamper, inverting and noninverting comparators, peak detector, and zero crossing detector are implemented using low-power folded cascode operational amplifier (op-amp) implemented using CNFET. The proposed CNFET-based analog signal processing applications are instigated at 32 nm technology node. Simulation results show that the proposed applications are properly implemented using novel folded cascode operational amplifier (FCOA) implemented using CNFET.

Field effect transistors (FET) based on Single-Walled Carbon Nanotubes (SWNTs) become the hot topic in fields of nano-electronic, clinical diagnostics, environmental testing etc. in recent years. In this paper, we reported a simple, scalable way to enrich semiconducting SWNTs by using HNO3/H2SO4. Then carbon nanotube field-effect transistors (CNTFET) biosensor was fabricated with the enrichment SWNTs for Escherichia coli O157︰H7 detection. The response of each CNTFET was monitored in real time before and after introduction of the Escherichia coli O157︰H7 at various concentrations. The results show that CNT-FET biosensors we fabricated are sensitive to change of concentration of solution and response time is really short.
