Effective Drive Current in CMOS Inverters for Sub-45nm Technologies

Hu J., Park J-E, Freeman G., Wong H.S.P., Stanford University, US

We propose a new model for the effective drive current (Ieff) of CMOS inverters, where the maximum FET current obtained during inverter switching (Ipeak) is a key parameter. Ieff is commonly defined as the average [...]

Simulating CMOS Circuits Containing Multiple FET Types Including the Geometric Dependence of Correlation between FET Types

Park J-E, Park S-J, Liang C-H, Assenmacher J., Watts J., Park J-E, Park S-J, Wachnik R., IBM, US

MOSFET device of similar design but different threshold voltage are often built on a single chip. It is important to be able to simulate with a compact model the variation of such devices including the [...]

Modeling MOSFET Process Variation using PSP

Watts J.S., Lee Y.M., Park J-E, IBM, US

The PSP model has been extensively evaluated for it’s abililty accurately match IV and CV characteristics MOSFETs measured on a single die. This enables accurate prediction of circuit behavior for circuits made of transistors which [...]
