abstract = {Run-time device-level reconfigurability has the potential to boost the performance and functionality of numerous circuits
beyond the limits imposed by the integration density. The key ingredient for the implementation of reconfigurable
electronics lies in ambipolarity, which is easily accessible in a substantial number of two-dimensional materials, either
by contact engineering or architecture device-level design. In this work, we showcase graphene as an optimal solution
to implement high-frequency reconfigurable electronics. We propose and analyze a split-gate graphene field-effect
transistor, demonstrating its capability to perform as a dynamically tunable frequency multiplier. The study is based on
a physically based numerical simulator validated and tested against experiments. The proposed architecture is evaluated
in terms of its performance as a tunable frequency multiplier, able to switch between doubler, tripler or quadrupler
operation modes. Different material and device parameters are analyzed, and their impact is assessed in terms of the
reconfigurable graphene frequency multiplier performance.},
