Patent ID: 8886149

Claim:
An apparatus comprising: a state machine coupled to a first estimation circuit and a second estimation circuit, the state machine configured to provide feedback to a first amplifier and a second amplifier, to a first filter, and to a mixer, the state machine configured to increase a bias current of at least one of the first amplifier and the mixer, or decrease a gain of at least one of the first amplifier and the mixer, or both increase the bias current and decrease the gain, when a voltage or power measured by the first estimation circuit is greater than a first predetermined threshold, a voltage or power measured by the second estimation circuit is less than a second predetermined threshold, and the first filter is set to a first bandwidth, the state machine further configured to decrease a gain of at least one of the first amplifier, the second amplifier, and the mixer when the voltage or power measured by the second estimation circuit is greater than the second predetermined threshold and the first filter is set to the first bandwidth.
