Exploiting ambipolarity in graphene field-effect transistors for novel designs on high-frequency analog electronics
Francisco Pasadas, Alberto Medina-Rull, Francisco G. Ruiz +8
Exploiting ambipolar electrical conductivity based on graphene field-effect transistors has raised enormous interest for high-frequency (HF) analog electronics. Controlling the dev…
Characterization of the Intrinsic and Extrinsic Resistances of a Microwave Graphene FET Under Zero Transconductance Conditions
Xiomara Ribero-Figueroa, Anibal Pacheco-Sanchez, Aida Mansouri +7
Graphene field-effect transistors exhibit negligible transconductance under two scenarios: for any gate-to-source voltage when the drain-to-source voltage is set to zero, and for a…
A Graphene Field-Effect Transistor Based Analogue Phase Shifter for High-Frequency Applications
A. Medina-Rull, F. Pasadas, E. G. Marin +5
We present a graphene-based phase shifter for radio-frequency (RF) phase-array applications. The core of the designed phase-shifting system consists of a graphene field-effect tran…
Sensitivity Analysis of a Graphene Field-Effect Transistors by means of Design of Experiments
Giovanni Spinelli, Patrizia Lamberti, Vincenzo Tucci +2
Graphene, due to its unique electronic structure favoring high carrier mobility, is considered a promising material for use in high-speed electronic devices in the post-silicon ele…
Large-signal model of 2DFETs: compact modeling of terminal charges and intrinsic capacitances
Francisco Pasadas, Enrique G. Marin, Alejandro Toral-Lopez +5
We present a physics-based circuit-compatible model for double-gated two-dimensional semiconductor based field effect transistors, which provides explicit expressions for the drain…
Radio frequency performance projection and stability trade-off of h-BN encapsulated graphene field-effect transistors
Pedro C. Feijoo, Francisco Pasadas, José M. Iglesias +3
Hexagonal boron nitride (h-BN) encapsulation significantly improves carrier transport in graphene. This work investigates the benefit of implementing the encapsulation technique in…
