BOOSTING CIRCUIT AND RFID TAG INCLUDING BOOSTING CIRCUIT |
摘要 |
One object is to provide a boosting circuit whose boosting efficiency is enhanced. Another object is to provide an RFID tag including a boosting circuit whose boosting efficiency is enhanced. A node corresponding to an output terminal of a unit boosting circuit or a gate electrode of a transistor connected to the node is boosted by bootstrap operation, so that a decrease in potential which corresponds to substantially the same as the threshold potential of the transistor can be prevented and a decrease in output potential of the unit boosting circuit can be prevented.
