CMOS 90nm Low-Power Rectifier Design for RFID Tags<br />
Shu-Yi Wong, M.A.Sc. Student<br />
Supervisors: Dr. C. Chen, Dr. J. Wu<br />
A Passive RFID tag obtains its power<br />
from the rectifier circuit, i which<br />
h<br />
harvests energy from the ambient RF<br />
field. High power conversion<br />
efficiency (POE) is vital but<br />
convention methods hd only <strong>of</strong>fers a<br />
Half-bridge Rectifier<br />
maximum POE <strong>of</strong> 37%. This research<br />
shows how and where (see bottom<br />
right-hand side) a POE <strong>of</strong> 74% can be<br />
obtained from CMOS bid bridge-rectifierifi<br />
(top), leading to a solution for<br />
difficult-to-meet RFID operating<br />
conditions.<br />
