Abstract
This investigation presents a low power wake-up detector design to monitor wakening signals in a FlexRay-based car network. The detector is required to wake up the bus driver that is operated in the idle low power mode provided that a wakening signal appears. The proposed detector utilities two low-power comparators with hysteresis function to carry out the required wake-up function and state recognition at the receiver end of the FlexRay bus.
