Patent ID: 7746216

Claim:
A device comprising a circuit arrangement for an RF transponder, said circuit arrangement comprising: at least one power input adapted to have electrical operating power applied thereto; at least one control input adapted to have at least one electrical control signal applied thereto; a first storage arrangement that is connected to said at least one control input to receive said at least one control signal, and that is adapted to produce and store a control state of said circuit arrangement in response to and dependent on said control signal when said operating power applied to said power input is at or above an adequate level; a second storage arrangement that is connected to a first output of said first storage arrangement to receive said control state, and that is adapted to hold said control state at least temporarily when said operating power applied to said power input is below said adequate level; and a signal output arrangement configured to receive an output of said second storage arrangement and a second output of said first storage arrangement, and to provide an output signal, wherein the second output of said first storage arrangement is inverted with respect to the at least one control signal.
