The settling time of a wireless receiver is reduced by providing a
previously utilized gain control state value to a low noise amplifier
(LNA) of a receiver front end during a warm-up portion of a wake-up
period of the wireless receiver which follows a sleep period. One
illustrative method includes the steps of receiving a notification signal
which indicates that the wireless receiver is to be placed in a sleep
mode, reading a gain control state value from a gain controller based on
receiving the notification signal, storing the gain control state value
in memory, providing the stored gain control state value from the memory
to the wireless receiver during a warm-up period of a second wake-up
period following the first wake-up period, and providing a gain control
state value from the gain controller to the wireless receiver based on a
signal level of a currently received signal of the wireless receiver
after the warm-up period.
