Patent ID: 7885600

Claim:
A 60 GHz radio frequency identification (RFID) tag integrated circuit (IC) comprises: an antenna structure on a die, wherein the antenna structure is sized for operation in a 60 GHz frequency band; a power recovery circuit on the die, wherein the power recovery circuit converts a radio frequency (RF) signal received via the antenna structure into a supply voltage; an oscillation module on the die and powered by the supply voltage, wherein the oscillation module produces an oscillation having a frequency approximately equal to a carrier frequency of the RF signal; a data recovery module on the die and powered by the supply voltage, wherein the data recovery module is clocked via the oscillation to recover data from the RF signal; a processing module on the die and powered by the supply voltage, wherein the processing module processes the recovered data and, when indicated within the recovered data, generates RFID tag response data; and transmitting circuit on the die and powered by the supply voltage, wherein the transmitting circuit provides the RFID tag response data to the antenna structure for transmission as an RF RFID response signal.
