In this work, an analytical current transport model of Graphene Nanoribbon (GNR) Tunnel Field Effect Transistor (T-FET) is presented considering drain source voltage (VDS), gate source voltage (VGS), carrier mobility (μ) and top gate dielectric (tOX). For a GNR width of 5nm at 0.275eV band gap, ON current of 1605 μA/μm is calculated with a very high ON/OFF current ratio of 107. Subthreshold slope...
In this paper, utilization of energy recovery techniques in carbon nanotube field-effect transistor (CNT-FET) circuits is discussed. Four different energy recovery techniques for complementary on-chip CNT-FET XNOR/XOR circuits are extensively studied and simulated using Cadence® Spectre simulator. The simulation results show that the power density of CNT-FET circuits is much higher than...
We present, implementation of a built-in current sensor (BICS) which takes into account the increased background current of defect-free circuits and the effects of process variation on ?IDDQ testing of CMOS data converters. A 12-bit digital-to-analog converter (DAC) is designed as the circuit under test (CUT). The BICS uses frequency as the output for fault detection in CUT. A fault is detected if...
In this paper, we propose a circuit model of the multi-walled carbon nanotube (MWCNT) based on our one-dimensional fluid model, which describes the electron transport in single-walled carbon nanotube (SWCNT). The performances of MWCNT and SWCNT in high frequency (RF/microwave) applications are then simulated using these models and compared with Cu interconnect. Simulations show that MWCNT interconnects...
This abstract describes the design, fabrication and testing of microfabricated 100 GHz coupled-cavity backward wave oscillator (CCBWO), which is operated in space harmonics -1 at 12 kV and 50 mA with round-beam radius 0.18 mm. The RF performance has studied using 3-D electromagnetic field simulator and particle-in-cell code. The cold-test assembly has been fabricated. The complete device assembly...
In this paper, a CNT interconnect model is presented and combined with a CNT-FET model to study the performance of CNT-FET circuits at very high frequencies. An all complementary CNT-FET inverter pair using CNT interconnection is modeled and characterized. Cadence/Spectre simulations show that CNT-FET circuits can operate at GHz frequencies and CNT interconnects are able to provide enough bandwidth...
In this paper, the classic wire-length estimation problem is addressed and a new statistical wire-length estimation approach that captures the probability distribution function of net lengths after placement and before routing is proposed. These types of models are highly instrumental in formalizing a complete and consistent probabilistic approach to design automation and design closure where, along...
