Patent ID: 7853230

Claim:
A method for controlling a gain state of a wireless receiver, the method comprising the steps of: receiving, during a first wake-up period of the wireless receiver, 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 during the first wake-up period, and storing the gain control state value in memory; in response to the notification signal: causing the wireless receiver to be placed in the sleep mode; in response to expiration of a sleep mode timer for the sleep mode: entering into a second wake-up period; providing a selection signal for selecting, via a multiplexer, the stored gain control state value from the memory to the wireless receiver; running a warm-up period timer for a warm-up period of the second wake-up period; and in response to expiration of the warm-up period timer: switching from selecting, via the multiplexer, the stored gained control state value from the memory to the wireless receiver to selecting, via the multiplexer, a current gain control state value from the gain controller to the wireless receiver, the current gain control state value being based on a signal level of a currently-received signal in the wireless receiver.
