Abstract

We describe a general method for optimized design of CMOS operational amplifiers. We observe that the amplifier design problem, incorporating a wide variety of practical constraints, can be cast as a very special type of optimization problem called geometric programming, for which very efficient global optimization methods have recently been developed. As a result we can efficiently determine globally optimal amplifier designs directly from specifications on power, open-loop gain, bandwidth, and many other performance measures.
