Nanoelectronic differential amplifiers and related circuits implemented on a segment of a graphene nanoribbon

Номер: US20120001689A1

Автор: Lester F. Ludwig

Принадлежит: Pike Group LLC

A multiple transistor differential amplifier is implemented on a segment of 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 graphene nanoribbon and a transistor in another portion of the graphene nanoribbon are responsive to respective incoming electrical signals. 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. In an example application, the resulting circuit can be used to interface with electrical signals of nanoscale sensors and actuators,
