Power consumption management based on receiver parameter and method for use therewith

摘要

An integrated circuit (IC) includes an RF receiver having an AGC module that generates an automatic gain control (AGC) signal based on a strength of a received signal, and a low noise amplifier that amplifies the received signal based on the AGC signal. A processing module generates a power mode signal based on the AGC signal, the power mode signal for adjusting a power consumption parameter of the IC based on the power mode signal.
