Batterieloses Informationsspeichermedium zur leistungsfähigen Datenübertragung |
摘要 |
A no-battery information storage medium (100) has a radio communication function of receiving power while receiving an externally transmitted radio wave as modulated data, and transmitting data outside the medium. One transmission/reception antenna coil (101) performs transmission/reception. A first full-wave rectifying circuit (11) is constituted by four rectifying elements connected to each other by bridging connection and connected to the two terminals of the transmission/reception antenna coil (101). A second full-wave rectifying circuit (14) is constituted by four rectifying elements, including two shared rectifying elements of the four rectifying elements constituting the first full-wave rectifying circuit (11), connected to each other by bridging connection and connected to the two terminals of the transmission/reception antenna coil (101). A power generating means (103) is connected to the output of the first full-wave rectifying circuit to generate power to be used inside the information storage medium (100). A transmission control means (105) is connected to the output of the second full-wave rectifying circuit (14) to substantially change a current in the transmission/reception antenna coil in accordance with transmission data, thereby transmitting the data. <IMAGE> |
