Simulator Based Simplified Design Approach of a CMOS 2-Stage Opamp

Ashis Kumar Mal, Abirjyoti Mondal, Om Prakash Hari, and Rishi Todani

Abstract—Two stage (Miller) opamp is one of the most commonly used opamp architectures in analog and mixed signal design. This paper presents the design of a Miller opamp using Potential Distribution Methodology (PDM). It is observed that a wide variety of design objectives depend on distribution of voltages and currents across the differential and gain stage. These dependencies are exploited to optimize the opamp performance and simulation results are presented.

Index Terms—CMOS, opamp, PDM
