RFID USING AN HYBRID ON-CHIP-OFF-CHIP TRANSFORMER
First Claim
Patent Images
1. A radio frequency identification (RFID) system comprises:
- an RFID reader coupled to transmit first electromagnetic signal via an off-chip winding section of a hybrid on-chip-off-chip transformer; and
an RFID tag coupled to receive the first electromagnetic signal via an on-chip winding section of the hybrid on-chip-off-chip transformer, wherein the on-chip winding section derives a second electromagnetic signal from the first electromagnetic signal when the on-chip winding section is within a proximal coupling distance of the off-chip winding section.
