Abstract

A radio frequency circuit is generated as an integrated circuit that is arranged to provide transmission, receipt, and storage of data. The data is transmitted and received across a radio frequency band. An antenna is included within the integrated circuit, wherein the antenna is manufactured at the time the integrated circuit is manufactured. A power source is mounted adjacent to the integrated circuit. The integrated circuit and the power source are encapsulated within the same integrated circuit package.

Claims

1. An apparatus, comprising:

an integrated circuit that is arranged to provide transmission, receipt, and storage of data, wherein the data is transmitted and received across a radio frequency band;

an antenna that is included within the packaged integrated circuit, wherein the antenna is manufactured at the time the integrated circuit is manufactured;

a power source that is mounted adjacent to the integrated circuit; and

a integrated circuit package that includes the integrated circuit and the power source.

2. The apparatus of claim 1, wherein the integrated circuit package corresponds to a standard integrated circuit package.

3. The apparatus of claim 1, wherein the power source corresponds to a Microelectromechanical Systems (MEMs) die.

4. The apparatus of claim 1, wherein the power source is mounted on the same chip carrier with the integrated circuit.

5. The apparatus of claim 1, wherein bond wires directly connect the integrated circuit to the power source.

6. The apparatus of claim 1, wherein the power source generates power for the integrated circuit by turning mechanical energy into electrical energy according to the Piezo electric affect.

7. The apparatus of claim 1, wherein the power source corresponds to mounted rare earth magnets and vibrating arms with a metal coil that produce electric power from the electromotive force of the changing magnetic fields enclosed by the moving coil.

8. The apparatus of claim 1, wherein the antenna is manufactured from a top layer of metal associated with the integrated circuit.

9. The apparatus of claim 1, wherein the antenna corresponds to at least one of the following:

a patch, a slotted patch, or a spiral antenna.

10. The apparatus of claim 1, wherein the integrated circuit further comprises an analog compensator, wherein the analog compensator provides analog adjustments to operations of the integrated circuit when the analog adjustments are determined necessary from at least one of operation and wafer tests of the integrated circuit.

11. The apparatus of claim 1, wherein the integrated circuit further comprises a flash memory, wherein the flash memory is arranged to store updates to the integrated circuit.

12. The apparatus of claim 1, wherein the integrated circuit further comprises passive filters that are arranged to determine the logic levels associated with a received signal.

13. The apparatus of claim 1, wherein the integrated circuit further comprises phase locked loop that is arranged to determine the logic levels associated with a received signal.

14. A single integrated circuit package, comprising:

an integrated circuit that includes;

18. The single integrated circuit package of claim 14, wherein the receiving side of the integrated circuit is further configured with a phase locked loop to determine logic levels for symbols associated with received data.

19. A system, comprising:

means for determining whether a radio frequency channel is in use;

means for transmitting data across the radio frequency channel;

means for receiving data across the radio frequency channel;

means for determining whether the data received corresponds to data from a master node;

means for determining whether the data received corresponds to data from a simple node when the radio frequency channel is shown to be in use; and
