Data detector for UHF RFID tags

摘要

A method of detecting a signal in radio frequency identification (RFID) transponder (FIG. 1) is disclosed. The method includes receiving a signal (FIG. 7) having a first time in a first logic state (high) and having a second time in a second logic state (low). A weight (700, 702) is determined in response to the first time and the second time. An output signal (from A2D) is produced in response to the weight and one of the first and second logic states.
