Patent ID: 8565135

Claim:
A system for use in a wireless device, the system comprising: first wireless protocol circuitry, wherein the first wireless protocol circuitry is configured to receive and process first signals according to a first wireless protocol; a power controller coupled to the first wireless protocol circuitry, wherein the power controller is configured to control power consumption of elements of the first wireless protocol circuitry based on a current state, wherein the power controller is configured to: in response to the first wireless protocol circuitry being in a listening state, lower power consumption of one or more first elements of the first wireless protocol circuitry; in response to the first wireless protocol circuitry being in a receiving state, return power consumption of the one or more first elements to a higher power level, wherein the one or more first elements comprise a first analog to digital converter (ADC), wherein lowering power consumption of the one or more first elements of the first wireless protocol circuitry comprises disabling the first ADC, and wherein, in response to the first wireless protocol circuitry being in the listening state, the power controller is configured to increase a clock rate of a second ADC, wherein, at the higher clock rate, the second ADC is configured to perform analog to digital conversion for the first ADC.
