Graphene FETs have gained rapid popularity after recent successful attempts at fabricating these devices on a Silicon substrate, along with capabilities of mass reproduction. A popular application of such devices is the single transistor RF mixer, which is capable of operation in the GHz range. In this paper, we present a novel configuration of Graphene FETs that can act as an averaging circuit simultaneously for both digital and analog valued signals. In combination with MOS circuits, they are also capable of acting as summing circuits. Simulation results are included to verify the accuracy of the resultant operations.
