      Current-mirror-based potentiostats suffer from systematic and random errors causing offset, gain and linearity error in reading out the sensor data. In this work, a new potentiostat topology is proposed to eliminate the ...
    • RF performance projections of graphene FETs vs. silicon MOSFETs 

      Rodriguez Duenas, Saul; Vaziri, Sam; Ostling, Mikael; Rusu, Ana; Alarcón Cot, Eduardo José; Lemme, Max (2012-08)
      Open Access
      A graphene field-effect-transistor (GFET) model calibrated with extracted device parameters and a commercial 65 nm silicon MOSFET model are compared with respect to their radio frequency behavior. GFETs slightly lag behind ...
