Abstract
Various techniques for dynamically reducing power usage in a wireless receiver are disclosed. A receiver unit receives a wireless signal over a channel and processes the wireless signal, including dynamically changing one or more of the settings of the receiver unit to control its power usage. These setting are changed in response to one or more power setting values that are generated based on a first set of information that includes state information for the channel. The receiver unit may dynamically change a first setting that causes the bias current applied to an analog-to-digital converter to be changed. The channel state information may include information indicative of a received signal strength indication (RSSI), information indicative of a packet error rate (PER) for packets encoded on the wireless signal, and header error check (HEC) and/or cyclical redundancy check (CRC) errors for data packets encoded on the wireless signal.
