Abstract
In a wake-up control device for waking up a peripheral circuit such as a transmitter/receiver in a radio communication device, during a standby time in which an RF unit and a processing unit are powered off by a switch, an RF signal is received to produce a detection signal by a detector. The detection signal is transferred to the wake-up controller to be sampled. The header and other fields are detected and counted. A control signal is in turn produced by the respective counts to turn on the switch.
