Abstract

The invention provides a simulation model for realizing radio frequency identification and a simulation method of the simulation model. The simulation model comprises a signal source model, a card reader model and a tag model, wherein the signal source model is used for outputting a synthetic signal, the synthetic signal is synthesized from carrier waves and signal waves; the card reader model is used for inputting the synthetic signal and outputting a first electromagnetic signal to the tag model; and the tag model is used for receiving the first electromagnetic signal and outputting a second electromagnetic signal to the card reader model. The signal source is approximate to a true signal source, and simulation errors can be reduced. Therefore, through the simulation model, simulation errors can be reduced, and the precision of a simulation result is improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor manufacturing, in particular to a simulation model circuit for realizing radio frequency identification and a simulation method thereof. Background technique [0002] RFID (Radfo Frequency Identification) technology is a non-contact automatic identification technology, which transmits signals through electromagnetic waves or inductive coupling to complete automatic identification of target objects. Compared with other automatic identification technologies such as barcodes, magnetic cards, and contact IC cards, RFID technology has the advantages of no manual intervention in the identification process, multiple targets can be identified at the same time, a large amount of information storage, and it can work in various harsh environments. Therefore, RFID technology has been widely used in fixed asset management, production line automation, animal and vehicle identification, road toll collectio...
