Very low power active RFID receiver |
摘要 |
A receiver includes two receiving modules, where the first receiving module is extremely parsimonious on battery power and as long as it is successful in developing a proper output signal at a given port maintains the second receiving module off, or substantially off. When the signal output of the first module drops below a preselected output, the second receiving module is enabled to develop and apply an output signal to the given port.
