Abstract: A transceiver with wake up detection includes a primary control unit, a transmission unit and a receiving unit, the transmission unit comprises a first logic set, a second logic set, a third logic set, a first loop, and a second loop. The first loop outputs a first differential signal, and the second loop outputs a second differential signal. The receiving unit comprises a wake up detection circuit having a first comparator, a second comparator and a fourth logic set. When the first comparator and the second comparator receive a first predetermined level of the first differential signal and a second predetermined level of the second differential signal, the fourth logic set outputs an idle state signal and a data signal to the primary control unit to make an operation mode of the transceiver switched from a low power mode to a normal mode.
