On wafer testing of RFID tag circuit with pseudo antenna signal

摘要

An RFID tag circuit is described having a pair of signal paths that flow to an input of a demodulator of the RFID tag circuit. A first of the signal paths couple the demodulator to an antenna port of the RFID tag circuit. A second of the signal paths couple the demodulator to a location where a pseudo antenna signal first appears on the RFID tag circuit while the RFID tag circuit is being tested on-wafer.
