Frequency compensation techniques for monolithic amplifiers

Integrated circuit amplifiers are a common building block in many analog systems. For high performance applications, high gain amplifiers are used with heavy feedback. For versatility as a feedback amplifier, the open loop response should not exhibit an excess of uncompensated poles. Previously, the necessary frequency compensation has not been achieved in fully integrated amplifiers. Bulky discrete element RC circuits have been connected to external terminals provided on the integrated circuit for such purpose.
