Abstract
Proposed is a dual band RFID tag including a first rectifier configured to receive and rectify a first RF signal modulated at a first frequency, a first regulator configured to regulate an output voltage of the first rectifier, a second rectifier configured to receive and rectify a second RF signal modulated at a second frequency, a second regulator configured to regulate an output voltage of the second rectifier, a voltage distributor connected to a first node and a ground in a state of being positioned therebetween, the output terminal of the first rectifier and the output terminal of the second rectifier being both connected to the first node, a multiplexer configured to output any one of an analog detection signal output from a sensor and an output signal of the voltage distributor, in response to a first selection signal or a second selection signal, and an analog-to-digital converter configured to receive as an operating voltage a voltage of a second node to which an output terminal of the first regulator and an output terminal of the second regulator are both connected and to convert an output voltage of the multiplexer into a digital signal.
