PARALLEL STAGE POWER OUTPUT RECTIFIER FOR RADIO-FREQUENCY IDENTIFICATION (RFID) DEVICES, AND RELATED COMPONENTS AND METHODS
摘要
<p>Parallel stage power output rectifiers for radio-frequency identification (RFID) devices and related components and methods are disclosed. An RFID tag receives a radio-frequency (RF) signal comprising RF input energy through an input such as an antenna. The RF input energy provided to a rectifier splits the RF input energy into two or more stages having parallel electrical outputs. The parallel electrical outputs allow for a more efficient use of the input energy in terms of current draw and improves voltage droop, thus improving the range and operation of the RFID tag.</p>
