| Abstract: | In this paper, we propose a new approach for the robust design of complementary metal‐oxide‐semiconductor amplifiers based on settling‐time specifications. The approach is based on the definition of the separation factors and on the analysis of their role in the settling time. We define a design strategy for being certain that an OTA satisfies the settling‐time constraint under any statistical variation of process or design parameters. The proposed strategy is applied to the transistor level design of a two‐stage amplifier and a three‐stage one. Simulation results, in good agreement with theory, confirm the validity of the proposed approach. Copyright © 2016 John Wiley & Sons, Ltd. |
