This paper describes a method for connecting an MOSFET 2-D device simulator to a circuit simulator via a 3-D table look-up MOSFET model. The computational cost of the device simulator is drastically reduced by a proposed monotonic piecewise cubic interpolation technique. With this technique, the device simulator needs to calculate only 100 ~ 200 points to make up an accurate 3-D table look-up MOSFET model. The computational time necessary for the interpolation is only about one third of the time for calculating one current point by the device simulator.
