A Novel Analysis of Periodic Structures Based on Loaded Transmission Lines
Periodically loaded transmission lines are characterized by a frequency response with regular pass and stopbands. Interestingly, each of the passbands exhibits a peculiar comb-alike behavior, in which again, nested (or internal) pass and stopbands can be identified. In this work, we focus our…

Design of GFET-based reconfigurable voltage-controlled amplifiers and analog phase shifters for high-frequency applications
Abstract This work presents a reconfigurable radiofrequency (RF) circuit based on a single graphene field-effect transistor (GFET), capable of operating as an analog phase shifter, a voltage-controlled amplifier, or both, while maintaining precise control over gain and phase. The circuit exploits…

Variability Assessment of the Performance of MoS2-Based BioFETs
Two-dimensional material (2DM)-based Field-Effect Transistors (FETs) have been postulated as a solid alternative for biosensing applications thanks to: (i) the possibility to enable chemical sensitivity by functionalization, (ii) an atomically thin active area which guarantees optimal electrostatic…

A Graphene Field-Effect Transistor Based Analogue Phase Shifter for High-Frequency Applications
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 transistor (GFET) used in a common source amplifier configuration. The phase of the RF signal is controlled by exploiting…

On the impact of the output conductance on high-frequency amplification in graphene transistors
Abstract In contrast to the impressive dynamic current gain and cut-off frequency demonstrated by graphene field-effect transistors (GFETs), which compete with mature high-frequency (HF) technologies, GFETs still stay behind their HF counterparts in terms of power amplification and maximum…
