摘要： Identification information is wirelessly communicated between radio frequency devices. In one embodiment, a first wireless device transmits a signal to request identification information. Other wireless devices are each affixed a respective item, and each of the other wireless devices determines if a reply signal is to be transmitted, and if so, communicates the reply signal to the first wireless device.

摘要： To identify an RFID tag in a field of RFID tags, an interrogator sends a series of commands to implement an arbitration scheme. The commands include differentiation, selection, and modulation information. The tag uses the differentiation information to differentiate commands sent by the interrogator from commands sent by other interrogators that may be within communication range of the tag. The selection information is used by the tag to determine if the tag is a member of a group selected by the interrogator for response to the interrogator. If the tag is a member of the selected group, the tag may send a reply that is modulated using a modulation type selected by the modulation information. In accordance with one of the modulation types, one of three different pulse waveforms is selected by the interrogator via the modulation information to multiply with the baseband waveform of the reply from the tag.

摘要： A radio frequency identification device includes an integrated circuit including a receiver, a transmitter, and a microprocessor. The receiver and transmitter together define an active transponder. The integrated circuit is preferably a monolithic single die integrated circuit including the receiver, the transmitter, and the microprocessor. Because the device includes an active transponder, instead of a transponder which relies on magnetic coupling for power, the device has a much greater range.

摘要： A frequency doubler includes a first Gilbert cell, a second Gilbert cell coupled to the first Gilbert cell, a frequency generator configured to apply a first sinusoidal wave to the first Gilbert cell, and a phase shifter applying a sinusoidal wave shifted from the first sinusoidal wave to the second Gilbert cell. A method of doubling frequency without using a feedback loop includes providing a first Gilbert cell, providing a second Gilbert cell coupled to the first Gilbert cell, applying a first sinusoidal wave to the first Gilbert cell, and applying a sinusoidal wave shifted from the first sinusoidal wave to the second Gilbert cell.
