  • Passive RF tag with adiabatic circuits
    Patent number: 9495628
    Abstract: A passive tag embedded in a package includes multiple conductive coils. A first coil receives radio frequency (RF) energy used to power the tag. Additional coils receive and/or transmit data signals, clock signals, and carrier signals. The RF energy and other signals may be at different frequencies. An RF probe includes a first coil to emit the RF energy to power the tag. The RF probe includes additional coils corresponding to the additional coils in the tag. The RF probe may turn off the RF signal used for power during communication. The RF energy may be rectified to provide DC power to circuits in the tag, or may be used directly for adiabatic circuits. The RF probe and the package may have complementary shapes to facilitate alignment of the coils.
