• Bindal, Ahmet; Hamedi-Hagh, Sotoudeh 2006-01-01 This three-dimensional exploratory study on vertical silicon wire MOS transistors with metal gates and undoped bodies demonstrates that these transistors dissipate less power and occupy less layout area while producing comparable transient response with respect to the state-of-the-art bulk and SOI technologies. The study selects a single metal gate work function for both NMOS and PMOS transistors to alleviate fabrication difficulties and then determines a common device geometry to produce an OFF current smaller than 1 pA for each transistor. Once an optimum wire radius and effective channel length is determined, DC characteristics including threshold voltage roll-off, drain-induced barrier lowering and sub-threshold slope of each transistor are measured. Simple CMOS gates such as an inverter, two- and three-input NAND, NOR and XOR gates and a full adder, composed of the optimum NMOS and PMOS transistors, are built to measure transient performance, power dissipation and layout area.

Simulation results indicate that worst-case transient time and worst-case delay are 1.63 and 1.46 ps, respectively, for a two-input NAND gate and 7.51 and 7.43 ps, respectively, for a full adder for a fan-out of six transistor gates (24 aF). Worst-case power dissipation is 62.1 nW for a two-input NAND gate and 118.1 nW for a full adder at 1 GHz for the same output capacitance. The layout areas are 0.0066 μm 2 for the two-input NAND gate and 0.049 μm 2 for the full adder circuits • Annema, Anne J.; Geelen, Godefridus Johannes Gertrudis Maria 2001-01-01 A high-voltage level tolerant transistor circuit, comprising a plurality of cascoded transistors, including a first transistor (T1) operatively connected to a high-voltage level node (3) and a second transistor (T2) operatively connected to a low-voltage level node (2).

Ambipolar transistors are ideal candidates for the simple and low-cost development of complementary logic circuits since they can operate as n-type and p-type transistors. Nevertheless, the experimental demonstration of ambipolar organic complementary circuits is limited to inverters. The control of the transistor polarity is crucial for proper circuit operation. Novel gating techniques enable to control the transistor polarity but result in dramatically reduced performances.

Here we show high-performance non-planar ambipolar organic transistors with electrical control of the polarity and orders of magnitude higher performances with respect to state-of-art split-gate ambipolar transistors. Electrically reconfigurable complementary logic gates based on ambipolar organic transistors are experimentally demonstrated, thus opening up new opportunities for ambipolar organic complementary electronics. • Ghavami, Behnam; Raji, Mohsen; Pedram, Hossein 2011-08-26 Carbon nanotube field-effect transistors (CNFETs) show great promise as building blocks of future integrated circuits.

However, synthesizing single-walled carbon nanotubes (CNTs) with accurate chirality and exact positioning control has been widely acknowledged as an exceedingly complex task. Indeed, density and chirality variations in CNT growth can compromise the reliability of CNFET-based circuits. In this paper, we present a novel statistical compact model to estimate the failure probability of CNFETs to provide some material and process guidelines for the design of CNFETs in gigascale integrated circuits. We use measured CNT spacing distributions within the framework of detailed failure analysis to demonstrate that both the CNT density and the ratio of metallic to semiconducting CNTs play dominant roles in defining the failure probability of CNFETs. Besides, it is argued that the large-scale integration of these devices within an integrated circuit will be feasible only if a specific range of CNT density with an acceptable ratio of semiconducting to metallic CNTs can be adjusted in a typical synthesis process. • Feucht, Dennis 2010-01-01 This second volume, Designing Dynamic Circuit Response builds upon the first volume Designing Amplifier Circuits by extending coverage to include reactances and their time- and frequency-related behavioral consequences. • Chen, C-L; Kim, K; Truong, Q; Shen, A; Li, Z; Chen, Y 2012-01-01 A spiking neuron circuit based on a carbon nanotube (CNT) transistor is presented in this paper.
