—Beta-solenoids are a class of protein nanotube structures that are observed in virulence factors, prion proteins and amyloid fibrils. Here we investigate the compressive strength of the triple-beta-helix solenoid structure found in the cell puncture needle of the bacteriophage T4 virus. We characterize the compressive mechanical strength of this protein(More)
Triple-Gate FinFETs have been demonstrated to be promising to push further the down scaling of CMOS technology, because of their high immunity against the so-called short channel effects. However, due to their three-dimensional (3-D) architecture, strong degradation of their analog characteristics has been reported, basically due to large extrinsic(More)

In this paper, a semi-analytical extrinsic gate capacitance model for Triple Gate FinFET, based on three-dimensional numerical simulations, is presented. The model takes into account the source/drain electrode and contact areas. It includes 5 capacitance components that describe the different fringing electrical couplings that exist inside the FinFET(More)
In this paper we present the results of the implementation of a nanoscale double-gate (DG) MOSFET compact model, which includes hydrodynamic transport model, in Verilog-A in order to carry out circuit simulation. The model in Verilog-A is used with the SMASH circuit simulator for the analysis of the DC and transient behavior electrical CMOS circuits.(More)
A methodology to properly establish an accurate SOI FinFET compact model through SPICE simulator is presented. This compact model is implemented in Verilog-A to simulate the performance of RF circuits based on SOI FinFET technology. It predicts well static behavior of the transistor and circuit, as well as their small-signal RF behavior by modeling the(More)
