LNA's power consumption optimization

I designed an integrated wide-band LNA from 0.1GHz to 5GHz, NF and S parameters are good enough for requirements. However, I need to reduce power consumption without degrading LNA perfomance (NF and S parameters). How can I optimize LNA's power consumption?

In order to optimize a LNA you must define a FOM expression based on LNA's characteristics, such gain, noise, power consumption and other. Using a FOM in an optimization algorithm allows it to improve performance. On the other hand, such algorithm could be implemented by using genetic algorithms.

I want to implement an optimization algorithm ? can anyone please help me?
