A multiple transistor differential amplifier is implemented on a single graphene nanoribbon. Differential amplifier field effect transistors are formed on the graphene nanoribbon from a first group of electrical conductors in contact with the graphene nanoribbon and a second group of electrical conductors insulated from, but exerting electric fields on the graphene nanoribbon thereby forming the gates of the field effect transistors. A transistor in one portion of the differential amplifier and a transistor in another portion of the differential amplifier are responsive to an incoming electrical signal. A current source, also formed on the graphene nanoribbon, is connected with the differential amplifier, and the current source and the differential amplifier operating together generate an outgoing signal responsive to the incoming electrical signal. |
