An RFID tag includes: an antenna receiving an RF signal from a reader; an AFE (analog front end) generating voltage using the RF signal; and one or more switches interposed between the antenna and the AFE and controlling the connection between the antenna and the AFE through the switch operation.
摘要:
Provided is a radio frequency identification (RFID) tag whose data can be stably read at a long distance on the basis of a passive RFID tag. The RFID tag includes a rechargeable unit charged to a predetermined voltage, and a power source including a direct current (DC) power source including a rectifier for converting an RF signal into DC power and a regulator for supplying a predetermined DC voltage, an interceptor disposed between the rechargeable unit and the DC power source to connecting or disconnecting the power to the rechargeable unit, and an overvoltage preventor connected to an output terminal of the DC power source in parallel.
摘要:
A via forming method that includes forming via-holes in a substrate is provided. The method includes putting the substrate, having the via-holes, in a first solution to fill the via-holes with the first solution. Metal particles are sunk into the via-holes by supplying a second solution containing the metal particles to the first solution. A first curing process of heat-treating the substrate is performed so as to form vias in the via-holes. A multi-chip package that includes the substrate having the vias is also provided.
