SPICE Modeling of Hook Shaped Idsat Curve for I/O 2.5V MOS Transistors

Tan P.B.Y., Kordesch A.V., Sidek O., Silterra Malaysia Sdn Bhd, MY

In this paper, we demonstrated how we have modified the mobility equation to accurately model the I-V characteristics of I/O 2.5V MOS transistors. Our aim is to model the effect of mechanical STI stress in [...]

DC and AC Symmetry Tests for MOSFET Models

McAndrew C.C., Freescale Semiconductor, US

Symmetry around Vds=0 is a critical requirement forMOSFET models, e.g. as it affects the ability of a model tosimulate accurately distortion for some RF CMOS mixers.The Gummel Symmetry Test is, until now, the standardtest used [...]

Device Correlation: Modeling using Uncorrelated Parameters, Characterization Using Ratios and Differences

McAndrew C.C., Drennan P.G., Freescale Semiconductor, US

Partial correlations between parameters of different types of devices, such as effective channel lengthfor PMOS and NMOS devices, are often modeled and simulated statistically via correlation coefficients.However this is cumbersome and inefficient from a modeling [...]

Unified Statistical Modeling for Circuit Simulation

McAndrew C., Drennan P.G., Motorola, US

Accurate statistical simulation and modeling are important for IC design. Different types of statistical simulation require different types of statistical models. In this paper a unified approach to statistical modeling and characterization is presented. Based [...]
