EKV MOS Transistor Model For Ultra Low-Voltage Bulk-Driven IC Design

The paper addresses a development and evaluation of well-known EKV MOS transistor model with focus on the ultra low-voltage / ultra low-power analog IC design employing rather “exotic” bulk-driven technique. The presented contribution can be viewed as an extension of already established compact simulation model with modifications to the original parameter extraction flow. The article contains a brief description of EKV model fundamentals, a novel parameter extraction flow and most importantly, the comparison of developed EKV model with the foundry-provided BSIM model (v3.3) and the experimental measurement data obtained from prototype chip samples fabricated in 130 nm CMOS technology.
