A　module　of　genetic　algorithms　suitable　for　evolvement　analog　IC　is　designed,　which　don＇t　relate　with　specific　physical　circuits　and　has　excellent　transplant　ability.　With　the　help　of　the　interface　module,　the　module　adapted　well　to　evolvement　analog　filter　circuits　and　wide　band　high　gain　amplifier　etc　to　optimize　their　performance.　Using　SMIC　0.18m　CMOS　mixed　technology,　a　evolvement　AGC　amplifier　is　designed　and　tapeouted　successfully　which　has　30MHz　operation　frequency,　40dB-70dB　gain　adjustment　range.　When　output　power　is　elevated　maximal　values,　the　AGC　has-65dBm　ldB　compression　point,-56dBm　IP3.　The　circuits　can　be　optimized　using　the　core　module　of　Genetic　Algorithms　or　recover　from　failure.　The　results　testing　the　chip　and　the　module　show　that　performance　of　AGC　amplifier　conforms　to　excellent　features　expected　after　about　40　generations.　©　2008　IEEE.
