ACCURATE TECHNIQUE BASED ON GEOMETRIC PROGRAMMING FOR ANALOG CIRCUIT SIZING

Abstract

In this thesis, a new method for optimization of analog circuit is presented. It is based on the method of geometric programming for convex optimization. It uses a look-up table that holds the characteristics of MOS devices to speed up the optimization. A generic optimization system is implemented in C++ that utilizes the proposed method. The implemented system is described thoroughly. The method is proved to be very efficient as well as accurate in meeting the required circuit specifications. A novel method to optimize the circuit across PVT corners is also introduced. The results of a two-stage op-amp optimization are shown and appear to be superior to results of previous optimization methods.
