Abstract
One of the major parameters of an opamp is its gain-bandwidth (GBW). Because nowadays the analog systems are pushed to higher frequencies, the design of opamps with a high GBW becomes very important. An overview of design techniques to achieve the maximum GBW in a CMOS technology is presented. An analysis of different feedforward techniques and their effect on the settling time is studied.
