Design-Oriented Analytical Model for Nanowire Biosensors Including Dynamic Aspects

Jean-Michel Sallese, Farzan Jazaeri, Ashkhen Yesayan

Nanowire field-effect transistor (NW FET) biosensors are known to be highly sensitive devices that can detect extremely low concentrations of biomolecules. In this article, we present an analytical model alongside with numerical simulations to calculate th ...

Nanowire junctionless ISFET noise model in Verilog-A

Jean-Michel Sallese, Ashkhen Yesayan

In this paper, we validate the Verilog-A implementation of the nanowire ISFET model. Based on the developed code and EKV formalism, the flicker noise of the nanowire ISFET was studied. The Verilog-A code was validated by comparing the data obtained from th ...

Simplified EPFL HEMT Model

Jean-Michel Sallese, Farzan Jazaeri, Ashkhen Yesayan

This paper introduces a simplified and design-oriented version of the EPFL HEMT model [1], focusing on the normalized transconductance-to-current characteristic (Gm/ID). Relying on these figures, insights into GaN HEMT modeling in relation to technology of ...

Analytical Modeling of Double-Gate and Nanowire Junctionless ISFETs

Jean-Michel Sallese, Farzan Jazaeri, Ashkhen Yesayan

In this article, we present a theoretical analysis of a junctionless (JL), ion-sensitive, field-effect-transistor (ISFET), self-consistently combining the electrochemical interaction between the semiconductor-insulator interface and the surrounding electro ...

Charge-Based Modeling of Double-Gate and Nanowire Junctionless FETs Including Interface-Trapped Charges

Jean-Michel Sallese, Farzan Jazaeri, Ashkhen Yesayan

Nanowire (NW) semiconductors are interesting devices for being used as sensors. Such NWs are doped silicon channels with electrical contacts at both ends, which is a kind of the so-called junctionless (JL) device. However, in contrast with the state-of-the ...

Explicit drain current model of junctionless double-gate field-effect transistors

Jean-Michel Sallese, Ashkhen Yesayan

This paper presents an explicit drain current model for the junctionless double-gate metal-oxide-semiconductor field-effect transistor. Analytical relationships for the channel charge densities and for the drain current are derived as explicit functions of ...

Physics-based compact model for ultra-scaled FinFETs

Jean-Michel Sallese, Ashkhen Yesayan, Christophe Lallement

A physical and explicit compact model for lightly doped FinFETs is presented. This design-oriented model is valid for a large range of silicon Fin widths and lengths, using only a very few number of model parameters. The quantum mechanical effects (QMEs), ...
