Summary:An optimization design technique to obtain global solution for a two-stage operational amplifier （opamp） with frequency compensation is presented. This frequency compensation technique can adjust the equivalent resistance to guarantee that the phase margin is stable even though circumstance temperature varies. Geometric programming is used to optimize the component values and transistor dimensions. It is used in this analog integrated circuit design to calculate these parameters automatically. This globally optimal amplifier obtains minimum power while other specifications are fulfilled.
