Analysis of the Influence of Substrate on the Performance of On-Chip MOS Decoupli

Abstract

tract—The interaction between substrate and devices is normally neglected during the design of on-chip MOS decoupling capacitors (decaps). However, it may significantly influence the decap performance to reduce high-frequency power supply noise. In this paper we propose a novel six-parameter analytical decap model which accounts for substrate and device interactions. Our model has been compared against state-of-the-art decap models. Moreover, it has been extensively validated through simulations a
