Circuit and method for reducing mobile station receiver power consumption by dynamically controlling linearity and phase noise parameters

A method, comprising:

• measuring channel power with respect to a receiver received signal;
• adjusting receive signal path gain within the receiver;
• comparing a current channel gain setting for the receiver to a threshold;
• and
• if the current channel gain setting is less than the threshold, then decreasing current within at least a portion of the receiver.

A receiver, comprising:

• a circuit that determines whether a single tone interferer is present with respect to a receiver received signal;
• an automatic gain control circuit for setting a current channel gain for the receiver;
• a processor operable to compare the current channel gain setting for the receiver to a first threshold and, if the current channel gain setting is less than the first threshold, issue a first decrease current command;
• and
• a first current control circuit coupled to at least a portion of the receiver and operable responsive to the first command to decrease current consumption by that portion.
