Smart AGC for wideband multi-standard RFIC

An automatic gain control (AGC) module for a wireless communication system comprising a plurality of amplifiers, the AGC module comprising:

• a receiving mechanism configured to receive an input that indicates a total amount of gain adjustment;
• a gain-control engine configured to:
• obtain a number of parameters associated with the amplifiers;
• determine a performance requirement required by a currently active wireless communication standard;
• and
• generate a gain profile for the amplifiers based on a combination of:
• the obtained parameters associated with the amplifiers, the total amount of gain adjustment, and the performance requirement required by the active wireless communication standard;
• and
• an output mechanism configured to output a plurality of control signals based on the generated gain profile, wherein a respective control signal controls gain of a corresponding amplifier, thereby enabling the wireless communication system to achieve the total amount of gain adjustment while meeting the desired performance requirement.
