<p>An RFID tag includes a matching circuit connected between the antenna and the ASIC. The matching circuit rotates the load impedance of the ASIC to provide optimal impedance matching between the antenna and the ASIC over a wide range of operating frequencies. The matching circuit includes a capacitor, first and second microstrips, and a capacitor connected in series. Another capacitor connects ground to a node between the first capacitor and the first microstrip.</p> |
