发明名称 Methods and apparatus for reducing power consumption of an active transponder
摘要 A power management method for a transponder having a plurality of circuits including at least a first circuit having a first active state requiring at least a first power level, and a second circuit having a second active state requiring at least a second power level greater than the first power level includes receiving a reader device signal in the first circuit, determining in the first circuit, based on information included in the reader signal, whether the reader signal requires a circuit other than the first circuit to operate, and causing the first circuit to provide a wake-up signal and the reader signal to the second circuit if it is determined that the reader signal requires a circuit other than the first circuit to operate. The wake-up signal causes the second circuit to move from an inactive state to the second active state.
