Graphene Transistors Do Triple Duty in Wireless Communications

Abstract:
Researchers have already made blisteringly fast graphene transistors. Now they've used graphene to make a transistor that can be switched between three different modes of operation, which in conventional circuits must be performed by three separate transistors. These configurable transistors could lead to more compact chips for sending and receiving wireless signals.

Chips that use fewer transistors while maintaining all the same functions could be less expensive, use less energy, and free up room inside portable electronics like smart phones, where space is tight. The new graphene transistor is an analog device, of the type that's used for wireless communications in Bluetooth headsets and radio-frequency identification (RFID) tags.
