Abstract—This paper presents both an integrated energy supply
and detection circuits for an RFID localization system. The equa-
tions to calculate the expected AC antenna voltage are presented as
well as a fast method to calculate the expected output voltage from
a rectifier. An ultra low power voltage detection circuit is described
which monitors the output voltage of the rectifier and consumes
only 3 nW. Also the input of the rectifier is monitored by
